Internet dating site wikipedia org

Men and women may also have an erection of their nipples when they are sexually excited, or if they feel cold.Nipples do not have any tissue in them that fills with blood.It is widely believed that a man's penis needs to be erect in order for him to take part in sexual intercourse and penetrate his partner's vagina and to ejaculate semen, but all are possible without an erection. Tissues in the penis called the corpus spongiosum penis and corpora cavernosa penis fill with blood, causing the penis to become longer, thicker, harder and to stand upright.In a healthy male, an erection will usually occur if the man is sexually aroused (made sexually excited) or stimulated. This happens to all healthy adult males of all ages. A man's erection usually stops if he is no longer sexually aroused, or after he has had an orgasm and has ejaculated.A man who often has problems having or keeping an erection of his penis is said to have erectile dysfunction (ED).On the other hand, an erection that lasts too long is also a dangerous condition called priapism.Some slang terms for having an erection are getting hard, getting wood and having a hard-on, and an erect penis is informally called a boner, hard-on, stiffy, wood or woody.This cross-section of a penis (what you would see if a penis was sliced across its middle) shows the two corpora cavernosa penis near the top surface of the penis and the corpus spongiosum penis (which used to be called the corpus cavernosum urethræ) surrounding the urethra near the bottom surface. It has a duct or tube called the urethra running right through it.

Pictures of men with erections appear on ancient objects and in paintings.The clitoris also has a corpora cavernosa, and when a woman is sexually excited this part of the clitoris fill with blood.This causes the clitoris and other parts of the woman's sex organs to become larger, harder, redder in colour, and very sensitive to being touched.The penis usually needs to be at least mildly erect before the man can have an orgasm and ejaculate semen.The scientific name for an erection is tumescence (which means "swelling").
