The prostate is a gland inside a male body, about the size and shape of a chestnut. The gland is located immediately in front of the rectum and its primary function is to make some of the fluid found in semen (most semen is made by the seminal vesicle).

Some guys find that stimulation of the prostate is very sexually exciting. It is possible to stimulate the male prostate by inserting a (gloved, lubricated) finger or a penis (with a condom) into a guy's rectum. The prostate will feel like a soft, spongy spot. If and how a man likes to have this area touched is up to him. Talk with your partner about his preferences.
