She (was a) Male
I recently brought this really cute girl back to my place after chatting her up at the local bar. But I never noticed the Adam's Apple on her neck until later that night.
When we were getting undressed, she took off her panties, and it just sort of hung there. I wasn't sure what to do. So I went for it.
We had gay s** for the next hour or so, and then she/he fell asleep. I took a shower, not exactly sure what to do after that.
The worst part? It was a lot better than s** with my ex-girlfriends.
