Embarrassing sex stories?

I wanted to hear some of your embarrasing stories, so I will shre one of mine to start off.

My SO is very sensitive around blood, it makes him naseus and he can't stand to be around it. We were doing it in the shower once, and out of nowhere my nose just started bleeding like crazy!! The thing is, I didn't even realize it until I looked down and the water was red! He freaked out and had to get out of the shower because he thought he was going to puke.... Ew. Lol.
