It's definitely not you. I can't tell you how many times I've had similar things happen to me. For instance, last year, a good friend of mine began inviting me to hang out with a group of her friends, most of whom were guys. I hit it off fairly well with one of the guys, and we begun hanging out occassionally. I told him, the first day I met him, that I was a lesbian and he SEEMED to understand what "lesbian" meant. In fact, for my birthay, he bought me one of those "hot girl" birthday cards. I THOUGHT the message had been received. Apparently not! Later that night, at my birthday party, he made sure he was the last to leave (which was awkward in itself) and, as soon as we were alone in my house, he tried to put the moves on me! It was absolutely terrifying! Over the years, I've countless male "friends" try to convince me that I'm not "really" a lesbian and should "try" having sex with them because they could "convert" me. Yuck! It's made it virtually impossible for me to have any straight male friends. Guys will usually respect a woman who is in a relationship with another guy and not try to put the moves on her-- but it's as though a lesbian is fair game. It's disrespectful, arrogant, homophobic, and disgusting. And my straight girlfriends don't understand how offensive and scary it is to have a big, straight dude coming at you, saying he can "convert" you. They will sometimes say I'm "too hard on guys" or "too cold" because I refuse to flirt back or wink at them or give them a false indication of interest. I frequently get the moves put on me when I DON'T show interest-- I'm afraid what would happen if I gave them a possible opening! (Plus I HATE it and can't get away from them fast enough!)
