OK here's one that isn't for the ladies. This is a picture of a male tarantula's "junk". This is called a palpal emboli and is what he inserts into the female to transfer sperm. He has one on each of the pedipalps, the small legs in the very front.
The male will make a sperm web and deposit sperm on it. He'll then use the palpal emboli to suck up the sperm and load them. Then if she's in the mood he will try, try again.
