Confused about my orientation

Hey guys, I know I haven't been here for a while, sorry.
Well basically, I started to realise that I'm attracted to girls and I think that I like a girl at my school. I think she's really great and I am attracted to her. I also find myself checking girls out but I never really thought about it before. I fell in love with a guy, and now I think I like a girl and I'm not sure if I'm bisexual or bicurious or my hormones are going crazy. I've seen two girl friends naked (we were in a bath together, it's complicated but there was nothing sexual about it) and it turned me on, and then the other day I accidentally saw a naked girl on someone's phone and that turned me on too.
But then I told a couple of friends at school that I think I'm bisexual and one of them called me an emo which I find kind of offensive because I'm definitely not an emo and I didn't know only emo's could be bisexual . I can't help that I'm attracted to girls as well as guys. Now I feel like I shouldn't be bisexual even if I am.
So I was thinking about my past to see any indications that I might be bisexual and then I remembered that I've got this thing that people might think I'm a lesbian for some reason, so I always try and not be affectionate around girls. I guess that's my fear of being judged or something.
As you might be able to tell, I'm quite quite confused and I just needed to rant really, get all my thoughts into order.

First off, There is nothing wrong with being bisexual!

Ok, got that? Now repeat with me...

Being bisexual doesn't mean you must be emo. Being bisexual doesn't make you less of a person. Being bisexual doesn't mean anything other than being able to be attracted to both men and women. I don't know how old you are, but it can be pretty tough to deal with when you first realize - there are so many myths out there, even among lesbian and gay people about us. But trust me, it gets better! I was 16 when I figured it out, and I'm 28 now. I've had satisfying relationships with both guys and girls, and my sexuality has never been an issue in them.

Wishing you the best!

I think you need to listen to your body, it will tell you even if your brain struggles with it. I figured out I was Bi at a conference... this woman walked into the room and the universe stopped and I nearly had to change my pants! Thankfully she is also Bi as is one of her children. She was in a relationship and wasn't interested in me anyway but she was able to be an awesome support and friend. After that so many relationships with other females in my life made a lot more sense!
Hang in there. We are here to talk to as you need.
