Explore the nuances of sexual response, from visual stimulation to physiological arousal, and discover factors like medication and aging that can influence sexual desire and performance. Learn about male and female responses, models of arousal, and the impact of aging on sexual activity.
E N D
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.
