Human penis
Ejaculation is when semen is pushed from the penis. It usually happens during an orgasm. Males can ejaculate during sexual intercourse or by masturbation. There are usually 40 million or more sperm in the semen ejaculated. Semen usually has a slight smell of chlorine and ammonia. It is not poisonous, but it is very bad if it gets in someone's eye. The enzymes semen contains to penetrate the egg in a female will also attack the eye. Be careful not to ejaculate into your eye or your partner's eye. Semen contains proteins and fructose (a kind of sugar.) Some people say it tastes sweeter if the man eats a lot of fruit. Scientists have not proven that. Smoking, or drinking coffee, tea or colas that contain caffeine can create a bitter flavor. Semen is slimy when wet. Eventually, it dries in the air and hardens like glue.
