Sex organ
A man's genitals are made up of many parts. The parts that can be seen on the outside of a man's body are his penis, which is shaped like a banana or a sausage; and his scrotum, which is a bag that hangs beneath the penis and contains the two testicles. A man's penis may be circumcised. A common slang, and slightly mean, word for the parts that can be seen outside the male body is "junk". For example, if a boy is naked, his sister might say, "Can't you wear a towel? Nobody wants to see your junk."
