What does this all mean?

I'm really confused about how I feel. I'm a girl and I currently have a girlfriend but sometimes I don't feel like I'm really gay but I don't feel like I'm straight or bi either. When it comes to women physically and emotionally I feel way more attracted to them than I do to men. I almost never find a guy attractive or even notice them but I seem to find multiple girls attractive and think about dating them. The thing is it seems like with girls I picture more of the emotional side and cute cuddling and kissing type of stuff with them and that kind of stuff makes me happy. Whats weird is with guys I don't think of any of that and I've never been a big fan of penises but if I watch porn, lesbian porn never turns me on but straight porn or something with a man (not gay male porn though) turns me on a lot. I don't understand what this means though. I've done a lot with my girlfriend but sometimes while we're doing stuff I don't feel as horny as I think I should be but I don't know if that means I don't like girls as much as I thought or if I'm just not as into her as I was before. I still like kissing her and making out with clothes on, its just once things heat up i stop enjoying it. What does this mean? Any advice to make things more clear to myself?
