Etymology

Origin of penis

First recorded in 1685–95, from Latin pēnis “tail, penis”; akin to Greek péos, Sanskrit pásas

Explanation

The penis is the male sexual organ. Boys and men and male animals all have penises. Kids and teens often giggle at the word penis, but it's just a word for a body part like "arm" or "leg." Well, a penis is a little different, since it's the organ males use for sex and urinating. Some men take a lot of pride in their penis, which in slang is most often called a dick. However, if you're talking about a dick with a parent or teacher, or you're writing about one in a paper, penis is the word you want to use.
