Okay this might be weird to think about. But have you ever wondered where sharks go to make their baby!? I just know they can't do it in the open. They probably got a share den or something??
@MaryBiWeeb I've watched a video of snails making love, and they don't have a gender. So they use this "sword" to define who be the mother. After they are done making love they're cum, comes out of the side of they're head.
