Human Sexual Response

Sexual Response Cycle Masters and Johnson’s four phase model Of sexual response.

Excitement

Phase 1 Vasocongestion increased blood flow to the genitals, causes the swelling of the female clitoris and labia minora and the erection of the male’s penis Vaginal lubrication begins and the labia majora begin to separate Female breasts enlarge Male testes swell and the scrotum tightens

Plateau

Phase 2 The female clitoris becomes highly sensitive and retracts under the clitoral hood to avoid direct stimulation or contact. The male testes withdraw into the scrotum The outer third of the vagina becomes especially engorged with blood and turns a dark purple color

Orgasm

Phase 3 In a female, the vaginal muscles contract and the uterus undergoes repeated ejaculated In a male, repeated contractions occur at the base of the penis and semen is ejaculated
