Understanding Human Sexuality

According to the research findings of Masters and Johnson,women are able to physiologically experience at least three types of orgasm: vaginal,clitoral and uterine.

Multiple orgasms are quite common for men and less common for women,but possible.

In Basson's intimacy model of sexual responses,people engage in sexual behaviours due to spontaneous sexual desire as well as due to motives to increase intimacy.

The physiological processes of vasocongestion and myotonia play a key role in the Masters and Johnson's stages of sexual response and Kaplan's triphasic model.

The one aspect of sex that is missing from all four models of sexual response presented in the text is memory.

The sexual response cycle from beginning to end for both the female and male is controlled completely by conscious perception of sexual stimuli by the brain.

When the male ejaculate empties into the bladder rather than going out the tip of the penis,this is called retrograde ejaculation.

The limbic system is central to female sexual response but it is less important in male sexual response.

The effects of hormones being present during prenatal development on genital anatomy or genitals are known as organizing effects.

The key hormones in sexual desire are androgens in both men and women.

The key organ in humans in responding to pheromones is the vomeronasal organ located inside the nose.

Due to the similarities between the clitoris and penis,the techniques involved in male and female masturbation are almost identical.

Sexual fantasies by women are more likely to focus on a role during sexual activity such as tying their partner up.

Females tend to have more fantasies about impersonal sex than males.

Close to 100% of people report having masturbated while viewing erotic images.

When the typical person thinks of two-person sex,one of the assumptions that most people will have is that the sex is heterosexual.

One of the best ways to find out how to use your hand to stimulate the genitals of a sexual partner is to find out how your partner masturbates.

Fantasies during two-person sex are very different from ones people have during masturbation.

Cunnilingus is only a heterosexual sexual activity,while fellatio is primarily a homosexual sexual activity.

If sex "just" consists of oral-genital contact it is impossible to transmit sexually transmitted diseases.
