I always thought I was bi, but now I'm not so sure

I'm twenty-two years old and first became aware of my attraction to women around the time I hit puberty. I didn't fully accept it, however, for another few years. I've always considered myself bisexual-- until extremely recently, I only dated men and found that, although it was difficult, I could orgasm with them.

However, I'm started to question just how bi I am, and am wondering if I might be a lesbian. I've begun to date women, and had my first kiss with one last night. It was nothing like kissing a guy. I can't stop thinking about it. The female body turns me on MUCH more than the male body. I've also had a problem when sexually intimate with men-- I clench up involuntarily. I'm not necessarily repulsed by the idea of being with them, it's just... not quite as arousing as the idea of being with a woman.

All my fantasies are about women these days. I feel like I can feel sexual attraction towards a man, but when it comes time to actually having sex, the feelings become muted. But if I have that sexual attraction to begin with (along with having orgasmed in the past), how can I be gay? But at the same time, if I clamp up when it comes time to have sex, how can I be bi?

I'm sorry. This is a bit of a rambling mess. I hope it makes sense to someone!

 

Thanks for your reply. I've been thinking it over, and I'm really starting to think I'm gay as well. Everything kind of makes sense that way. I think I might have a slight romantic attraction towards men, but not really a sexual one.
