Wikipedia Meaning and Definition on 'Erections'
An erection (pronounced ee-REK-shən) of a body part such as a man's penis, a woman's clitoris or a nipple refers to it becoming larger and harder.
The term erection is most often used to refer to an erection of the penis. 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. For an erection to take place, a man must be sexually aroused or stimulated (made sexually excited). This can happen if he is touched sexually, or even if he is not touched – for example, if he sees a naked person or thinks about having sex with someone else. 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. A man's erection usually stops if he is no longer sexually aroused, or after he has had an orgasm and has ejaculated. Blood flows out of the corpus spongiosum and corpora cavernosa penis, and the penis goes back to its normal size. 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.[See more about Erections at Dictionary 3.0 Encyclopedia]
