Define sexual scripts
Define sexual socialization
Understand the importance of Sexuality
Know the different sexual identities
Just a note to begin this chapter: sexuality is controversial. Even though it underlies many advertisement themes, is shown independent of any emotional or physical consequences in many TV and Big screen productions, and is commonly participated in outside of marriage, we are raised not to talk about it much. Many of us are even taught that religions are very strict on how sex is exclusively for married people, yet very few of us had the luxury of having our own parents teach us about it.
For some religious believers, it brings family shame to have sex outside of marriage. For others, the fear of God’s retribution shapes their very thinking about what sex is and how we should participate in it. Sociologists strive to maintain awareness of this while simultaneously preserving objectivity.
This chapter has two main goals: First, this chapter will hopefully help you to understand your own sexuality, body, and experiences. Second, this chapter will arm you with the understanding of the critical information you need to know about sexuality and sexual intercourse so that you can protect yourself and possibly others. Education is the most useful tool for protection.
A script is what actors read or study and what guides their behavior in a certain role. A script is a blueprint for what we “should do” in our roles. Sexual scripts are blueprints and guidelines for what we define as our role in sexual expression, sexual orientation, sexual behaviors, sexual desires, and the sexual component of our self-definition . All of us are sexual beings, yet none of us is exactly identical to another in our sexual definitions and script expectations. Having said that, keep in mind that we are not just born with sexual scripts in place; they are learned. Sexual socialization is the process by which we learn how, when, where, with whom, why, and with which motivations we are sexual beings.
We are all born with drives, which are biological needs that demand our attention and behavioral responses to them. The most powerful drives are circulation, breathing, voiding our urine and other waste, eating, drinking, sleeping, and sexual involvement. Sexual drives are biological urges to participate in sexual activity and in certain sexual roles.
Sexual scripts, once learned, will shape how that drive is answered. Sexuality is learned via culture and socialization. There are as many unique sexual scripts as there are people, yet some of these scripts have common themes and can be viewed as a collective pattern or trend in the larger social level.
Many of us learn our sexual scripts in a passive way. In other words, we don’t learn from experience, but from a synthesis of concepts, images, ideals, and sometimes misconceptions. For example, the commonly held belief that men and women are two different creatures, perhaps even from different planets, was a very successful fad in recent years that led an entire generation to believe that men might be from “Mars” while women might be from “Venus.”1
Today more and more people living in the U.S. have less religious values and more diverse experiences with sexuality. Further much of the younger generations’ focus on sex is on the orgasm. An orgasm is the sexual climax that accompanies sexual intercourse and includes muscle tightening in the genital area, electrical sensations radiating from the genitals, and a surge of a variety of pleasure-producing hormones throughout the body.
Many cultures have records of sexual expression and some even have records of sexual pleasure maximization.2
Some traditional sexual scripts that have been studied include a number of problematic assumptions. Some of these assumptions include but are not limited to: the man must be in charge, the woman must not enjoy (or let on that she enjoys) the sexual experience, the man is a performer whose skills are proven effective upon arrival of his partner’s orgasm, men are sexual while women are not, women can’t talk about it and turn to men for sexual interests and direction, and finally sex always leads to a female orgasm (her orgasm being proof of his sexual capacity). Numerous studies have shown that most of these traditional scripts are not realistic, healthy, conducive to open communication, nor negotiation of sexual needs and desires for couples. In sum, rather, these traditional notions can be an undermining influence in a couple’s intimacy. More contemporary scripts include these simple ideas:
Both partners need to learn to take ownership of the couple’s sexual experiences.
Both partners need to learn to communicate openly and honestly about their feelings.
Both partners need to learn to meet one another’s desires, needs, and wishes while making sure that their own needs are being met.
Genital Development
Many people think of male versus female reproductive and sexual body parts in terms of opposites. In sexual matters, men and women are very much alike from a physiological and biological point of view. We are even alike in our fetal development with our genitals developing from identical tissues, regardless of being male or female. Have you ever wondered why a pregnant woman can’t get an accurate ultrasound until the second month to determine the fetus’s sex being male or female? In part, technicians want to give the fetus enough time to develop genitals that coincide with the particular sex of the baby. More importantly, the fetus has identical genitals until about the 5 th -6 th week. That means it would require a DNA test to distinguish which sex the fetus is up until that point.
Sexually, males and females start with identical genital buds that usually form into the male or female reproductive organs. Figure 1 briefly discusses the development of male and female sexual parts from very similar genital pelvic tissues. Please note that sexual development is a natural yet extremely complex process that yields a mostly predictable outcome among newborns. That means most females are born with nearly identical sexual parts. Likewise most males are born with nearly identical parts.
Figure 1. Similar Sexual Development in the Male and Female Fetus.
With an XY male genetic configuration, the glans area will develop into the penis. The urethral fold will form the urethral meatus or opening in the penis. The urethral groove and lateral buttress will fold onto itself and fuse into the shaft of the penis with the urethra connecting the bladder to the urethral meatus or opening of the penis. The anal tubercle will form into the anus and external sphincter. The male glands (prostate, cowper’s, and seminal vesicles) develop in another process as do the testicles, which develop inside the abdomen then drop into the scrotum. Figure 2 shows an artist’s depiction of the tissues that biologists would use to identify the developing genitals of males and females.
Figure 2. How Male and Female Reproductive Parts Generate from the Identical Fetal Tissues.3
For the XX female genetic configuration, the glans becomes the clitoral glans; the urethral fold becomes the urethral meatus; the urethral groove and lateral buttress become the labia minora and majora (labia means lips); and the anal tubercle becomes the anus and external sphincter. The vagina, cervix, ovaries, and uterus form from other tissues. Interestingly, ovaries develop inside the abdomen. These basic fetal tissues differentiate because of the X or Y. In adult sexual partners these sexual parts function in very similar ways even though their placement and structure differ.
There are some variations when the actual physical sexual development does not follow expected patterns. Hermaphroditism is found among those variations and is reported in two forms. First, true hermaphroditism is an extremely rare condition wherein both reproductive organs of both males and females are in one person’s body and functioning to some degree or another (this includes, penis, testicles, prostate gland, vagina, uterus, and ovaries) . Second, pseudo – hermaphroditism (false or near Hermaphroditism) is a rare condition wherein some of both reproductive organs for males or females are present in one person’s body, but neither male nor female organs are completely present and/or fully functioning.
As is mentioned in Figure 2, not all fetal sexual development occurs uniformly. Though not discussed here in great detail, there are five common sexual development variations reported among newborns: Turner’s syndrome, Klinefelter’s Syndrome; Androgen Insensitivity Syndrome; Fetally Androgenized Females; and DHT-deficient Males. In most cases of fetal development, sexual development is predictable and follows the above mentioned pattern of originating from nearly identical tissues.
The Importance of Sexuality
Sexuality is important to us because it represents an activity that is a rite of passage into adulthood, because it is very pleasurable, and because it reinforces our roles and aspirations as males and females. Yet sexuality is truly a passive part of our daily lives. Samuel and Cynthia Janus published The Janus Report on Sexual Behavior in 1993. 4 They studied a scientific sample of 2,765 men and women and reported some general trends in U.S. sexual practices and patterns. They found that age-based estimates indicate a great deal of similarity in sexual frequency between age groups with 2-3 sexual encounters per week.
Sex is a minor (yet important) part of our daily time allocation. People with a sexual partner available have sex about 3 times per week, taking about 25 minutes per experience. That means about 75 minutes per week or 3,900 minutes per year is spent having sex. Divide 3,900 by 60 minutes, and it equals about 65 hours per year having sex. At first glance that sounds like a great deal of time allocation, but keep in mind that in comparison, most of us spend most of our lives doing nonsexual things.
Consider these estimates: if the average person sleeps about eight hours in a 24 hour period, works 8.5 hours, eats 1.5 hours, commutes .5 hour, watches TV for three hours, and spends about 2.5 hours for miscellaneous activities, then compared to routine non-sexual activities, sexual intercourse comprises a relatively small portion of our time (see Table 1).
Relatively speaking sexual intercourse is a passive part of the average person’s life accounting for only 65 yearly hours of involvement per year. Many people refrain from regular sexual intercourse until their twenties and are less likely to participate in it if they are not married than are married people. These estimations don’t take into account those with no sexual partner and those who abstain from sexual intercourse. The average would be much lower if those categories of people were averaged into the equation.

Sexual Anatomy
To understand our own bodies and also understand enough about sexuality to teach our children, we must understand the basics of female and male anatomy. Figure 3 shows an artist’s depiction of a cross section of female reproductive and sexual anatomy. The clitoris is extremely sensitive and is protected by the clitoral hood (not shown here). It sits above the vagina. In females, urine exits the body at the external urethral orifice (also called meatus). The vaginal orifice simply means the opening to the vagina itself. The labia are in two places, closer to the vaginal orifice (labia minora) and further away from the vaginal orifice (labia majora).
The urinary bladder sits behind the pubic bone and during urination travels an inch or two out of the body via the external urethral orifice. In the back and top of the vagina sits the cervix. The cervix is simply the window into the uterus. It is round, muscular and thick and has a small opening in it. The cervix is the bottom portion of the uterus (the uterus is where a fetus or baby would grow and develop during pregnancy).
The uterus leans forward toward the pubic bone. Inside the uterus on the left and the right sides are two small openings where the fallopian tube connects the ovaries to the uterus. There are two ovaries that have thousands of eggs in them at birth. A woman may release as many as 450 eggs during her reproductive years. After an egg is released from the ovary (ovulation), the fallopian tube carries the egg from the ovary down to the uterus. When pregnancy occurs it is often because sperm met the egg in the fallopian tube and fertilized it. Later, if the fertilized egg travels down the fallopian tube and implants into the uterus, then conception has taken place.
Figure 3. Female Reproductive and Sexual Anatomy, Cross-sectional View.4
The vagina is approximately three inches long and is made of tissues that are epithelial and mucosal. This means that when blood flow increases to the pelvis the vagina produces a lubricant in the form of moisture. The vagina is not hollow in the sense that a tube is round and hollow. The vagina is relatively flat and has potential space rather than constantly open space. The vagina has a band of pelvic floor muscles that surround it. One set of muscles is called the puboccocceygeus muscle (PC muscle) which is located approximately 1 inch inside the vagina and which also plays a role in sexual pleasure for both partners.
To truly understand how these parts function during sexual intercourse, we need to consider a research-based paradigm developed by Masters and Johnson years ago which they called the sexual response cycle. 5 The sexual response cycle is a model that explains how most people experience three phases when they engage in sexual intercourse: excitement, plateau, and then orgasm.
Masters and Johnson are quick to point out that each individual has a unique and varied sexual response so much so that no two sexual encounters would be expected to be perfectly identical between the same people. Nevertheless, these three phases are very common among most people.
As sexual intercourse begins both males and females pass through three phases.
Excitement phase is when blood flows to the pelvis bringing, more lymphatic fluid and
plasma to the region . Because of hormonal and psychological stimuli there is generally swelling in the sexual parts. While this is happening, the plateau phase begins which is when more hormones are released, moisture increases, heart rate increases, intensity of sensory perception increases (touch, smell, sight, hearing, and taste) . In the orgasm phase an electrical build up of energy is released that is associated with a rhythmic contraction of the pelvic floor muscles, the urinary and anal sphincters, and of various glands for males . This is called an orgasm. After the orgasm finishes, resolution eventually allows the sexual parts to return to pre-excitement conditions. These are almost identical in every way between males and females, except that there are differing sexual parts for each.
Thus, a sexual response in a typical female would typically follow a pattern similar to this one. In the excitement phase, blood and lymphatic fluids increase swelling inside the vagina. Hormones are secreted which lead to a mild uterine contractions which raise the uterus away from the pubic bone. The labia swell and the clitoris becomes hard. The vaginal tissues secrete moisture and the vagina itself lengthens and expands slightly inward.
The plateau phase begins as excitement continues. This causes the labia to become fully swollen, the clitoris to recede under the clitoral hood, and the uterus to become fully elevated (the hormone is called Oxytocin). The vagina is fully lengthened into the body, and, just before orgasm, lubrication ceases. During orgasm, the pelvis of the female experiences a series of contractions which occur every 8/10ths of second and can number anywhere from 1-20 or more in the sequence. The contractions include anal and urinary sphincter contractions, the smooth muscles in the inward portion of the vagina contraction, the puboccocceygeus muscle contraction, the uterine contractions which cause the uterus and cervix to dip down into the vagina, and general muscles contractions in the body.
Further, an electrical sensation surges from the clitoris radiating throughout the body and stimulates the pleasure centers of the brain and a release of the hormone called Oxytocin. When the orgasm ends, the body eventually returns to its pre-excitement state. In general, females have more capacity to experience more contractions over a longer period of time than do males. Females have been found to have much more capacity for sexual intercourse than males. This means females can have more sexual intercourse, more often, and with more orgasms than can the average male.
The male anatomy is presented in Figure 4. The male has a penis which is comprised of 3 spongy-like tissue columns that engorges with blood during excitement. A cross-section of the penis shows two outer columns and one column on the underneath side. The average male penis is just that—average. About 4-6 inches reported by Masters and Johnson. Since the vagina is 3 inches in length and has very sensitive regions near the outside of the vagina and not so sensitive regions deeper inside, the average male can satisfy the average female in heterosexual intercourse. Urine passes from the urinary bladder and exits at the external urethral orifice at the tip of the penis. The penis is attached inside the body to the pubic bone.
Figure 4. Male Reproductive and Sexual Anatomy, Cross-sectional View.6
There are two testicles inside a pouch called the scrotum. One testicle sits higher than the other. On the back of the testicle is a storage compartment where mature sperm end up before ejaculation. This is called the epididymis. There is a muscle called the dartos muscle (not shown) which elevates and lowers the testicle based on temperature and sexual pleasure. Sperm grow best at about 91 degrees Fahrenheit and most males are at about 98 degrees, so the dartos will raise and lower the testicles if in colder or warmer temperatures.
The testicles produce about 125-250,000,000 sperm every 3-4 days. More importantly, the testicles produce the sex-drive hormone called Testosterone. In males and females, higher levels of testosterone typically mean a higher sex drive (another similarity). The vas deferens will eventually carry the sperm from the epididymis out of the body during the orgasm. The prostate gland swells during excitement and fills with prostatic fluid. The seminal vesicle located above the prostate gland also swells and produces a fluid filled with natural sugars.
For males, in the excitement phase, blood and lymphatic fluids increase swelling inside the prostate, seminal vesicle, testicle, scrotum, and the penis. Hormones are secreted which lead to a higher volume of blood flowing into the spongy tissue columns of the penis than flow out. The penis erects this way (sometimes the penis will leak fluid and/or sperm before the orgasm, regularly referred to as “pre-cum”). The scrotum and dartos muscle draw both testicles up toward the pubic bone pressing the epididymis upward. As stimulation continues the swelling and fluid production continues to increase.
The plateau continues until just before the orgasm. When orgasm begins for males the penis is most erect. Males reach a point of no return in their orgasms (females do not). The ejaculation of sperm and fluids will continue in males, regardless of continued or interrupted stimulation. Females would experience an interruption of the orgasm when stimulation is interrupted. For males, the orgasm also includes a series of contractions which occur every 8/10ths of second and can number anywhere from 1-10. Most males will have 5-6.
The contraction includes: anal and urinary sphincter contractions; prostate and seminal vesicle contractions, dartos and scrotum contractions, pelvic floor muscle contractions; penile contractions; and a rhythmic sequence of these in such a way that the ejaculate is expelled from the body out through the penis. The sperm are released from the epididymis and travel through the vas deferens up and around the bladder then through the ejaculatory duct (where it picks up prostate and seminal fluids) and finally out of the penis. An electrical sensation surges from the prostate gland throughout the body and stimulates the pleasure centers of the brain and a release of the hormone called Oxytocin. For males and females Oxytocin brings a feeling of emotional connection.
After an orgasm, males may continue to experience an erection, but will have to wait a while for the central nervous system to reset before they can ejaculate or orgasm again. Most males wait less time when younger and more time when older. For males an ejaculation during orgasm would be expected, but sometimes ejaculations happen with or without orgasms, and orgasms may happen without ejaculations.
The Sexual Experience
Even though the physiological component of sexuality is common between males and females, the male and female sex drives are NOT identical. Studies consistently show that sexual desire for women is more sensitive to the context (meaningful or intimate connection) and the social and cultural environment (quality of relationships, stresses of the day, etc.). Generally speaking most men seek more sex than most women throughout most of the life span. Also, most men are more easily aroused by visual stimulation than are most women.
The Janus Report reported that 65% of men have an orgasm every time during love-making while females reported a much lower 15% every time. About 46% of women report “often” having an orgasm during love-making, compared to only 28% of men. 7 These sex drive differences also emerged in self -reported masturbation frequencies. About 55% of men and 38% of women masturbate on a daily-monthly basis.8
Numerous studies show that men and women enjoy sex most in a meaningful relationship, typically long-term committed ones. These studies indicate that the pleasure is more meaningful and enjoyable in long-term committed relationships. Figure 5 shows a pleasure and intimacy continuum for both sexes. Those who abstain from all sexual activity are in the lower left corner with no intimacy and no pleasure. Those who solo masturbate (by themselves) derive pleasure without intimacy. Those who purchase prostitution services derive pleasure, yet have very little intimacy. Finally, those who have one-time sexual encounters in a “one-night stand” also derive pleasure with little intimacy over time.
Figure 5. Pleasure and Intimacy Continuum for Both Males and Females.
For married or cohabiting couples, sexual intercourse includes both pleasure and intimacy. Newlyweds typically have their honeymoon night, and sex becomes a rite of passage that marks the beginning of their full emersion into the marital relationship. In time husbands and wives have sex for many of the other reasons listed in Figure 5. Sometimes one spouse has sex to meet the needs or wants of their partners. At other times sex is a healthy and fun stress relief. Sometimes sex is a convenient way to be affectionate as a giver and a receiver. In relationships, sexual intercourse has many functions including reinforcing commitment and loyalty with one another. To give and receive is pleasurable and bonding during sexual intercourse.
Some couples seeking parenthood will have sex to pleasure themselves while getting pregnant. Many report enhancements of intimacy with less focus on pleasure at moments such as these. Others get distracted because sex becomes goal-oriented rather than simply expressive while trying to make a baby. For long-term relationships that have endured challenges such as hardship, betrayals, offenses, anger, arguments and ultimately forgiveness, sexual intercourse takes on a profoundness of its own. Those who have short-term relationships miss out on the intimacy payoff that sex provides to those in long-term relationships. Sex becomes a unique way of enhancing trust and closeness while sometimes providing sexual healing to wounded egos and feelings.
Extramarital affairs are intimate relationships with a person other than one’s spouse that may be sexual or nonsexual. Most U.S. extramarital affairs are sexual and non-consented to by one’s spouse. In spite of a variety of estimates on how many married people were ever unfaithful to their spouse, all scientific studies have found that men were more likely than women to have an extramarital affair and that most men and women do NOT ever have an affair.
Marital infidelity has been and continues to be disapproved of by the general public. Many in the U.S. who disapprove of affairs, simultaneously understand the frailties of the human experience and sympathize to some degree with those who make this “mistake.” Such was found to be true with politicians, movie and TV stars, and sports celebrities (you can pick any one from the online list available on the Internet when you search “celebrity affairs”). Affairs don’t always lead to marital or relational dissolution, but in most cases it is better if the offending spouse or partner confesses the infidelity rather than simply gets caught.
Sexual Identity
Human beings are socialized into their adult roles and learn their sexual identities along with their gender roles, work roles, and family roles. Sexual orientation is the sexual preference one has for their partner: male, female, both, or neither. There are a few common sexual orientations that can be seen at the societal and personal level. Heterosexuality is the sexual attraction between a male and a female. Homosexuality is a sexual attraction between a male to another male or a female to another female. Bisexuality is a sexual attraction to both male and female sexual partners.
There is a difference in these three dimensions of sexuality: sexual orientation, sexual desire, and sexual behaviors. Sexual desire is the attractions we have for sexual partners and experience that exist independent of our behaviors. Sexual behaviors are our actual sexual actions and interactions. It is important to note that orientations, desires, and behaviors are not always the same thing. They do overlap at times. For example, a heterosexual male may have had a homosexual experience in the past, or not. He may at times desire males and females regardless of his actual sexual activities. A lesbian female may have had a short-term heterosexual relationship, yet define herself as a lesbian.
When considering the congruence of these three concepts it is helpful to use visual aids. Figure 6 below shows how sexual orientation, desires, and behaviors are at times congruent, meaning they correspond directly with each other; or incongruent, meaning they do NOT correspond together with each other. These three dimensions of our sexuality are surprisingly incongruent among adults in the U.S. society.
Figure 6 Sexual Orientation, Desires, and Behaviors: A Venn Diagram.
Edward O. Laumann et al . wrote the largest sociological study of U.S. sexuality ever published. 9 In this book he wrote about the prevalence of self-identified sexual orientations. Laumann and the other researchers surveyed about 3,400 respondents. By far, most members of U.S. society are heterosexual. Laumann avoided the use of the words “heterosexual” or “homosexual.” He found that 7.1% of males and 3.8% of females have had sex with a partner of the same sex. 10
Laumann also reported that over 96% of males and 98% of females identified themselves as heterosexual. Only two percent of males and 0.9% of females identified themselves as homosexual, while 0.8% of males and 0.5% of females reported bisexuality. The Janus Report also reported their findings on sexual behaviors and sexual orientation. Their sample reported 22% of men and 17% of women said yes to the question, “Have you had a homosexual experience?” 11
Janus also reported that 91% of men and 95% of women claimed to be heterosexual; four percent of men and two percent of women claimed to be homosexual; and five percent of men and three percent of women claimed to be bisexual. 12 Heterosexuality is by far the most common identification in studies where respondents are asked to identify their sexual orientation. 13 Yet, heterosexuals may have had a variety of sexual experiences in a variety of context and still consider themselves to be heterosexual in spite of dimensional discontinuity or continuity. Generally speaking Janus and Laumann found that the U.S. is a very sexual nation. They reported that very few men and women reported never having had vaginal sexual intercourse (less than five percent). They reported that men typically have sex sooner than women and that most had sex by age 20. Janus specifically reported that only nine percent of men and 17% of women had NO sexual experience before marriage. 14
Sexuality and Politics
Sexual orientation, desires, and behaviors have become extremely politicized. The largest sexual political action committee is the Human Rights Campaign, which emerged in the 1980s as a Gay Community Rights organization. LGBT and LGBTQ have replaced Gay Community as the collective acronym. LGBT stands for Lesbian, Gay, Bisexual, and Transgendered (occasionally Queer is added by some interest groups). The Human Rights Campaign has become the central political action organization for LGBTQ interest groups. 15
Marriage between same-sex couples became an emotionally charged political issue during the California Proposition 8 referendum and constitutional amendment that Passed November 2008. Because it passed, the California Section 7.5 of the Declaration of Rights to the State Constitution now reads, “Only marriage between a man and a woman is valid or recognized in California.” This set a strong national precedence against rights to same-sex couples to have legally recognized marriage on par with heterosexual married couples. Estimates are that over $80 million was spent on this proposition alone on both the for and against efforts. 16
The Prop 8 initiative originated from a political action committee called ProtectMarriage.com. It self-describes as a “…broad-based coalition of California families, community leaders, religious leaders, pro-family organizations and individuals…to restore the definition of marriage as between a man and a woman.” 17
Interestingly most in the U.S. would never oppose an individual’s choice or orientation when it comes to sexuality. This and other conservative interest groups like it have formed to advocate for conservative legislation and policies in the U.S. and abroad. None, on either side of sexual rights, assumes that this oppositional battle for rights, laws, and policies has ended. Many see the stakes as being higher than ever in the current sexual politics scene.
