Am I biual/?

This might sound incredibly stupid, but I just wanna know an outsiders opinion on this. My best friend and I (we're both girls) have had a "thing" for each other for a few years now (long time I know!) and the other day we got a little drunk and made out. But the thing is, she's a (and tells everyone this constantly), and I do like her (a lot) but I don't wanna BE with her because she's too, well, butch I guess. And I feel really bad for thinking this but I just wish she was more feminine. Oh God I so confused! See, I like guys too, but I the girls I like are usually feminine, cos well, I like them to be girls! Sorry if this doesn't make any sense. My question is this: am I , or even ? I'm asking this because although I like this girl, I don't want to be with her because she's too "manly". Am I just making excuses not to get with her because I'm actually straight or is it just because I like my girls to be feminine? Again, I'm sorry this is long and confusing.
