Ejaculation is when a male person (or other male mammal) shoots out liquid from his erect penis after it has been aroused or stimulated (excited sexually). It happens when he has an orgasm. This article is about ejaculation in human beings.[1]
When a man is stimulated, his penis becomes erect. When he has an orgasm, semen comes out from the end of his penis. Semen contains sperm and other substances. How long a man can be stimulated before ejaculating, how long the ejaculation lasts, the strength of the ejaculation, and the amount of semen that comes out, all vary from one man to another. When a man ejaculates, he has a very good feeling in his penis and in his groin area (the part of his body where his torso joins the top of his legs). A man can ejaculate after he masturbates, is touched by someone else sexually, and sometimes, even if he is not touched (for example, if he looks at pictures and videos on the internet that cause sexual arousal, or thinks about sex). Ejaculation can also happen without control when a man is sleeping, which is called a wet dream. Urine can sometimes also come out with the ejaculatory fluid during sex. Boys usually do not ejaculate until they reach puberty, but sometimes it can happen before.
Slang terms for ejaculation are blowing a load or blowing a wad, and busting a nut.[2] creaming, cumming, jizzing, nutting, jazzing, spurting, squirting and skeeting. Ejaculation takes place when the man has an orgasm (the height of sexual excitement), usually after his genitals have been physically stimulated in some way. However, ejaculation can also happen if a man has not been touched, for instance, if he becomes aroused or stimulated (made sexually excited) by looking at sexy pictures, watching sexy videos, or thinking about sex. When a man ejaculates while sleeping, it is called nocturnal emission.
