Visual stimulation • Self report = men respond more than women • Physiologically = both men and women have similar responses
What can cause you to not want sex? • Silence during sex play • (decreases arousal) • Birth control pills • Blood pressure medication • Antidepressant medication • Antihypertensive medication • Tranquilizers • High nicotine cigarettes
Basic physiological arousal responses • Vasocongestion • Orgasmic platform • Engorgement of outer third of vagina during plateau phase • Erection in men • Mytonia • Muscular spasms during orgasm • Uterine contractions
Vasocongestion • Female Stage #1
Vasocongestion • Female Stage #2
Vasocongestion • Female Stage #3
Sexual response models • Helen Kaplan’s modes • Masters and Johnson’s model
Helen Kaplan’s model • Desire • Excitement • Orgasm
Master’s & Johnson’s model • Excitement • Plateau • Orgasm • Resolution • Refractory period • Male only
Orgasm Male & female descriptions of orgasm are indistinguishable
Response differences between the sexes • Greater variability in female response • Male refractory period • Lack of this= multiple orgasms for women • Males • may have pre-ejaculatory orgasms followed by final orgasm
Grafenberg Spot (G-spot) • Upper wall of vagina • Possible remnant of prostate tissue • Sometimes results in ejaculation from urethra • Ejaculate fluid is similar to male prostate secretions
Aging and sexual response • Women • Decreased vaginal lubrication • KY or” Slippery Stuff” • Decrease in length & width of vagina • Decrease in number of orgasmic contractions
Aging & sexual response (cont.) • Men • Longer time to get erection • Erection goes away faster • Increased control • Reduced mytonia • Reduced testicle elevation • Less ejaculate • Lower force of ejaculation
Use it or lose it! • The more active you are during your life, the longer you will remain sexually active.
