Among men, differences in penis size are most apparent when fully erect during plateau in the flaccid, unaroused state during excitement

in the flaccid, unaroused state

occurs in a majority of women and in about one-fourth of men

Most substances that have a reputation for enhancing sexual desire or performance work because of chemicals in the substance that affect nerves in the penis or clitoris of chemicals in the substance that affect the brain of chemicals in the substance that affect blood flow of heightened expectations and the social situation

of heightened expectations and the social situation

The period of time after an orgasm in which it is physiologically impossible for a man to achieve another orgasm is called the plateau phase orgasmic platform excitement phase refractory period

refractory period

After sex, the return to the unaroused state is called the refractory period plateau resolution all of the above

resolution

In humans, erection of a man's penis results from spongy tissues filling with semen the pubic bone protruding into the penis spongy tissues becoming engorged with blood contraction of the bulbocavernosus muscle

spongy tissues becoming engorged with blood

motivated by relationship and intimacy needs very similar to men's the point at which the labia minora come together, stimulation of which is pleasurable the clitoris, stimulation of which is pleasurable the area on the front wall of the vagina that some women say is sensitive to touch the spot on a G-string that covers the vagina

the area on the front wall of the vagina that some women say is sensitive to touch

In women, nipple erection is likely to be most noticeable during the excitement phase the plateau phase, particularly just before orgasm orgasm it is equally likely for all of the above

the excitement phase

Which of these responses occurs in men during the excitement phase of sexual arousal? the testicles are elevated toward the body the testicles grow smaller and harder the Cowper's glands secrete fluids the testicles are lowered farther away from the body

the testicles are elevated toward the body

Research since Masters and Johnson has shown that there is very little variation in men's and women's sexual responses men's and women's sexual responses are very similar there is greater variation in men's sexual responses than is observed in women there is greater variation in women's sexual responses than is observed in men

there is greater variation in women's sexual responses than is observed in men

Some women emit a fluid during orgasm. The fluid comes from the urethra vagina seminal vesicles Fallopian tubes

urethra

When sexually aroused, the first physiological responses are erection of the penis in men and erection of the clitoris in women production of testosterone in men and production of estrogen in women secretions from the Cowper's glands in men and vaginal lubrication in women vasocongestion, leading to erection of the penis in men and vaginal lubrication in women

vasocongestion, leading to erection of the penis in men and vaginal lubrication in women

Masters and Johnson observed that when men and women are sexually stimulated, physiologically women respond slower than men women respond as fast as men women respond faster than men most women do not respond

women respond as fast as men
