STD jokes

My daughter asked me today:"Dad, What is sex?"

I had feared this moment would come and didn't think it would come this soon but nevertheless I was prepared. So I sat her down and explained it all. The birds and the bees, the different sexual orientations, all the positions and of course I had to mention all the STD's and the rules of safe sex. When I finished she looked at me shocked and confused: "So... which box should I check on this form? Male or Female?"

STDs are a lot like Pokemon...

It's hard to catch them all, but once you do, the game is pretty much over.
