Document Summary
Two basic physiological processes: vasocongestion: accumulation of blood in blood vessels of region of the body, especially genitals; swelling or erection, myotonia: muscle contraction. Corpora cavernosa and corpora spongiosum become engorged with blood. Vasodilation: arteries dilate to allow for strong flow of blood. Veins are compressed, restricting outgoing blood flow. Produced by direct physical stimulation of genitals, other parts of body, or erotic thoughts. Fluid from cowper"s gland appear at tip of penis as man gets closer to orgasm. Scrotal sac tightens and testes are pulled closer to the body: female. Vasocongestion of tissues surrounding vagina causes fluids to seem through the semipermeable membranes of vaginal walls. Relaxation of smooth muscles surrounding arteries supplying glans and crura of clitoris. Tightening of the bulbospongiosus muscle around entrance of vagina. Crura of clitorus and vesticular bulbs also swell. Upper two thirds of vagina expand dramatically: ballooning response. Breasts swell and enlarge, so nipples might not look erect: sex flush.
