Document Summary

Ppl been doing for hundreds of hundreds of years. But didn"t understand b/c ppl afraid to study. 1960s: masters and johnson gave first scientific account of human sexual response. Emphasized 2 systems in body: vascular system and neuromuscular system. Looked at changes that occur in these systems when ppl aroused. Penis not bone, muscle. it"s a pump into which blood flows (vasocongestion) Muscular: myotonia (increase in neuromuscular tension--body tenses. not as visible as erection, but toes curl, etc) Vascular: vaginal lubrication (vasocongestion: blood flows around inside of vagina and causes clear liquid to form on inner walls of vagina)--not as noticeable as erection, can be aroused and not know it. Some things erect on women: clitoris lengthens, nipples harden. Much different than in man (man localized to genitals, women=whole-body phenomena) Orgasmic platform: figure 2a. tissues inside engorge w/ blood to form, vagina balloons, uterus rises from pelvic cavity, clitoris changes position. Argument if separate stage (not much different)
