Dude, you've got felch all over your face. by Pymp November 01, 2003
A stripper told me she had a previous boyfriend that did this to her, and she said that was the best sexual experience she's ever had. Sounds disgusting to me.
You ever did that? You know anyone that's ever done that?
^^^ As far as the boyfriend in your example, if he purposely ate semen, he is gay. Or at least BI and has homosexual leanings.
No. Personally, I've never heard of anyone doing such a thing.
