How do gays not exist? I'm a man. I don't have sex with women. I only have sex with men. Gay. Exist.
Well this is close to being a decent reply, so well done on that.
But I don't see any proof.
I think it's obvious. You are a man, you DO have sex with women - in fact I will so so far to tell you you're married to a woman and you do sex in her.
