Document Summary

Phases: sexual response cycle in women: excitement phase: begins with vas-congestion. Walls of the vagina expand and lubricate. Can last from a few minutes to hours: plateau phase. Women often need more time than men to reach this phase. Can be uncomfortable if orgasm does not occur: orgasm phase. Pressure due to vas-congestion reaches a tipping point. About 8-15 contractions (first 5 or 6 more strong felt) Women often experience longer orgasmic contractions than men (more vas- congestion) All orgasm due to direct or indirect clitoral stimulation. Some women experience multiple orgasms (all are capable, generally requires direct clitoral stimulation: resolution phase. Heart and breathing rates return to normal. Sexual response cycle in men (same phases as women: excitement phase. If stimulation stops, testicles may be uncomfortable: plateau phase. Just before orgasm: glans penis becomes engorged & pre-ejaculatory fluid may appear: orgasm phase. Orgasm and ejaculation do not always occur together.
