I would say no to having had a same-sex experience, although one time may remotely qualify. Well over 10 years ago when I used to question my sexuality due to my dressing (even though I had relations with women and loved it) I was out one night (drab) with a big group and one of our friends was a good looking gay guy. Somehow the two of us ended up at my house alone and we were pretty drunk (which you would think would lower inhibitions.) I pretty much said to myself that if I had any doubt I should just figure it out. I went to my bed and hopped in and he did right after me. I really gave it a chance but couldn't even bring myself to touch or kiss him. I had to hop out and go sleep in the guest bed. It's just not in me, but I'm happy I gave it a chance to know for sure.
I don't have to ask a gay male friend "why don't you like women?" anymore. (I did once.) If they feel towards women like I do towards men then I guess I understand. From that moment I think I started being alot more accepting of all people. We're all different and there's nothing anyone can do to change that. And it's probably a good thing. How boring would this world be if we were all the same? Very!
Cheers to all.
