Yeah, I had an ugly experience with a guy. He was married, had a kid, but he also liked his own gender. Some day he tried with me.

I have nothing against each others' sexual interests, but I'm 100% hetero, so it was a ugly experience.
As for the topic: just ask the one out that you like the most, and let the others down GENTLY. And, a friendly advice, don't choose only by exterior beauty, but rather by character and beauty.
Slayer rules!!! Yeaaah, man!
