Confused

I think I might be gay, but than I think no I am not. I like guys. I really do, my friends would say I am obsessed, but in the back on my mind when I talk to her everything is more clear. I get nervous and every chance I get I talk to her. I’ve been thinking about my feelings for a long time, but maybe its just because I haven’t had a boyfriend in a really long time. I don’t really know what to think or do about this. My mom has asked me if I was a lesbian in the past and so have a few people at school actually. I said no to all of those, but maybe I am. This is the first time I am confronting this, and I don’t really think I understand what I am saying. Someone help please.
