Cock and balls
Situated next to the wall of the rectum, the prostate gland is about the size of a chestnut, and is connected to the bladder by one tube and to the urethra by another. While its purpose is not fully understood, amongst other things it produces the milky fluid in which sperm swim and live (making up about 30-40% of semen volume).
It also produces substances which give semen its characteristic smell and help pump the cum towards the end of the cock. It’s packed full of sensitive nerve endings which is why getting fucked or fisted can be a big turn-on.
