11 Sex Hormones and Sexual Behavior Sexual behavior among many lower animals is almost completely governed by hormones. Sex hormones have organizing and activating effects.An organizing effect would be the hormones predisposing lower animals toward masculine or feminine mating patterns.An activating effect would stimulation of the sex drive and facilitation of the sexual response.

17 The Sexual Response Cycle The sexual response cycle is characterized by vasocongestion and myotonia.Vasocongestion: Engorgement of blood vessels with blood, which swells the genitals and breasts during sexual arousal.Myotonia: Muscle tension.The sexual response cycle consists of four phases: excitement, plateau, orgasm and resolution.
18 Excitement PhaseExcitement Phase: The first phase of the sexual response cycle, which is characterized by erection in the male, vaginal lubrication in the female, myotonia, and increases in heart rate in both males and females.In the excitement phase, men experience an erection, the scrotal skin thickens and the testes become enlarged.In women, the vagina becomes lubricated, the clitoris swells and flattens. The breasts enlarge and blood vessels near the surface become more prominent.
19 Plateau PhasePlateau Phase: the second phase of the sexual response cycle, which is characterized by increases in vasocongestion, muscle tension, heart rate, and blood pressure in preparation for orgasm.In the plateau phase, breathing becomes rapid, like panting. Heart rate may increase to 100 to 160 beats per minute.In men the head of the penis shows some size increase and in women, the outer part of the vagina swells, contracting the vaginal opening in preparation for grasping the penis.
20 Orgasmic PhaseOrgasmic Phase: The third phase of the sexual response cycle, which is characterized by pelvic contractions and accompanied by intense pleasure.In the male, semen collects at the base of the penis and muscle contractions propel the ejaculate out of the body.Orgasm in the female is manifested in 3 to 15 contractions of the pelvic muscles that surround the vaginal barrel.
21 Resolution PhaseResolution Phase: The fourth phase of the sexual response cycle, during which the body gradually returns to its prearoused state. Unlike women, men enter a refractory period.Refractory period: A period of time following orgasm during which an individual is not responsive to further sexual stimulation.

24 RAPE Rape: Forced sexual intercourse. 4 out of 5 rapes are committed by people the victims know.More than one out of three men in one study admitted to coercing women into sexual activity.
25 Why do Men Rape Women?Some social scientists argue that rape is often a man’s way of expressing social dominance over women.Alcohol figures prominently in rape.American culture socializes men into becoming rapists by reinforcing males for aggressiveness and competitive behavior.Men may misread women’s resistance as a game of playing hard to get.Men may delude themselves into thinking that “women actually want it.”
26 Myths About RapeIn the United States there are many myths about rape…myths that blame the victim.Examples include “the woman is partly to blame if she dressed in a provocative manner.” or “women like to be talked into sex.” or “women say no but actually mean yes”Men who support traditional, rigidly defined gender roles are more likely to blame the victims of rape.

28 Preventing RapeFrom a sociocultural perspective, preventing rape involves publicly examining and challenging widely held attitudes that contribute to rape.On a personal level, there are things that women can do to protect themselves such as establishing signals with women in your local area, keeping windows locked, avoiding deserted areas and not talking to strange men on the street.
29 Preventing Date Rape Communicate your sexual limits to your date. Meet new dates in public places, and avoid driving with someone you’ve just met.State your refusal in definitive terms.Become aware of your fears.Pay attention to your “vibes.”Be cautious if you are in a new environment.If you’ve recently broken off a relationship with someone, don’t let him into your place.Stay sober and see that your date does too.
