Maybe once or twice. I don't really go for straight guys unless I am under the impression he is gay.
Once I was at friend's house party and I was chatting with this guy. He kept hyping up his muscles and was like 'go ahead and touch them,' so I did and told him they were nice

I swore he was 100% gay, but I don't believe he is. I did run into him at a gay club last year with a mutual lesbian friend. Mess he has a gf of like a year.
I had this one friend who was really cute and we'd joke around a lot. I've probably drunkenly told him 'if you were gay...' Who knows!
