women don’t want any further stimulation, with dissipation of sexual arousal. Multiple orgasms in women are more possible than in men. There are several hormones that are involved in sexual arousal. These include estradiol, cortisol, and testosterone. Testosterone has been most studied and it has been studied primarily in men. There does appear to be some relationship, however, between testosterone and measures of sexual arousal in women as well.
THEORIES ON SEXUAL RESPONSIVENESS While there are several theories on sexual responsiveness, none of them have been flushed out to the degree that has been done by the work of William Masters and Virginia Johnson, who wrote a book on the subject in 1966. They list several phases of physiological responses to different kinds of sexual stimulation that was referred to as the human sexual response cycle. These are the different stages or phases of the sexual response cycle: It starts with the excitement phase, also called the arousal phase. Things like erotic stimuli which, as you know, can be of several different types. The body prepares itself for sexual activity. Foreplay happens in this phase, which varies among individuals and in different social and cultural contexts. In both men and women, the excitement phase involves an increased breath rate, an increased heart rate, and a rise in the blood pressure. More than 80 percent of women and more than fifty percent of men say that nipple stimulation enhances this response. There can be a sex flush because of increased blood flow to the skin. The flush happens in the upper torso, the face, the hands, and the feet but it can affect the whole body. This flush generally goes away after an orgasm. There will be an increase in muscle tone in the excitement phase, which may be voluntary or involuntary. The anal sphincter contracts when touched. Males will experience some degree of erection and the testes are drawn toward the body. The scrotum tenses up and gets thicker. In women, there is congestion of the vagina, labia
