Document Summary

Sexual response typically progresses in 3 stages: excitement: male erection, female vag lubrication (vasocongestion, orgasm: intense sensation that occurs at peak of sexual arousal, resolution: body returns to unaroused state. Vasocongestion: accumulation of blood in the blood vessels in the genitals in which a swelling or erection results. Myotonia: muscle contractions not only in genitals but throughout body. Vaginal lubrication: result of vasocongestion, capillaries in vaginal walls dilate and blood flow increases, fluids seep through semipermeable membranes of vaginal walls. Orgasmic platform: tightening of the entrance to vagina caused by contractions of bullbospongiosus muscle that occur late in the arousal stage of sexual response: estrogen helps the vasodilation, upper 2/3rds of vagina expands in a ballooning" response. Sex flush: resembles a measles rash often beginning on upper abdomen and spreads over chest: appears on the skin of both males and females, but usually females.
