In reality my "Str8 / Gay" level is probably dead on bi. I enjoy sex with both. I had two long term girlfriends (one lasted 4 yesrs, the other 5 years).
I've never been shy about having sex, talking about sex, etc. I was at a party some 7 years ago and there was this very beautiful and sexy young lady who I had been friends with for over a year (she was 21 I was 30) and the topic of sex came up.
I was in a dry spell being single at the time and she complained that of those she COULD find none could do it right. i.e. she liked rough sex.
Well we both had a bit much to drink, and we were both within walking distance of our respective abodes, BUT - mine was much closer - it was cold so I invited her to stay at my house to sober up or at least stay the night.
Once we got there - again the topic came up about not being able to find someone who could do rough sex right. I told her I could as a friend help her out. She said, I doubt it, you're gay. At this point we had a short discussion on safe words limitations and such - don't draw blood - some bruising is ok - respect etc. "I don't really see the point though" she said.
She got a stinging slap and a stern lecture from me about doubting my words as a reply. She looked surprised -I grabbed her by the shoulders and threw her onto the bed and well - lets say it was a VERY enthusiastic and fun evening. We were both bruised but sated by the end of the night. In the morning she wanted a repeat - and that night as well - and one more night before begging to "have some time off to recuperate." She was walking a little funny by then.
She and I are on friend terms to this day though no repeats. She did brag a bit to our circle of friends about my prowess in bed - which was awkward for a while but oh well. But by far she is one of the top two sex sessions I've had.
In closing I prefer relationships with men. They seem to have less drama and for me thats what I prefer. Every woman I was in a relationship with would try to "figure out what I was feeling" and I'd be honest, and they wouldn't believe me. It got old.
