Document Summary
Hypothalamus is the seed of the pleasure system. Three different female response: arousal stages in women tend to be less defined: each women has different intensity. 30-40% by 18 years old had an orgasm/masturbation. Erection: parasympathetic is highly active in the morning (penis is hard, sympathetic system role in ejaculation. In the typical male response, arousal stages are well defined: excitement > plateau > orgasm > resolution. Orgasms among males by 18 years old over 92% have orgasms and/or masturbated. Female hyenas have such big clitoris that it looks like it"s having a clitoris erection (bigger than the male hyenas). So orgasm can be a vestigial thing. Orgasm seems to be affective with pigs: fertility went up by 6, fertility rates go up with new method of orgasm. Rates of sexual intercourse slowly drop as you start to age. The average student thinks about sex a lot.
