Guilt of Coming Out Of The Closet?

I'm currently in the closet about my sexuality but not for the reason you think. I'm bisexual and have known this ever since I was six I probably Like Boys 60% girls 40%. I recently came out to myself about 2 months ago. Nobody knows that I'm bisexual except for me.So anyway last year at my school a guy came out and he got alot of attention from some of the girls. Some of my friend and I (Before I came out to myself) joked around and said he's probably not gay and only said so to get attention from the girls. Anyways now it's summer and I feel like I want to come out but I probably only want to come out to get attention from the girls because before this I never had the courage to come out and kept it to myself. Now im stuck if I come out I'll feel guilty there are many Gays,Bisexuals,Lesbians,Pansexual,etc. who wanted to come out because they felt trapped and guilty while I only want to come out to get attention not from just the girls but from many people. So I'm thinking of just staying in the closet until I stop being a attention hog. Either way I still don't feel very comfortable about it people at my school will probably start rumors like the ones I started about that guy who came out. And there are still many homophobes in my school they'll probably tease me but I'm not bothered by that I'm bothered about the other stuff I talked about. This may be confusing but thats how I feel. I was confused for years I had a fear of being Gay/Bi now I kind of have a fear of being straight.... Yup not very ordinary :I And just incase you want to know I mainly watch gay porn. But if I had the choice to be with a girl or a boy in a relationship I would pick a girl.I'm not very attracted to the Penis or Vagina I haven't seen vagina that much but when I saw a picture I almost gagged I used to gag at the sight of penises But i'm getting kind of used to it and It can be somewhat attractive at times. I would also like you too tell what my sexuality probably is because I'm kind of confused. Sometimes I think I may be straight and i'm convincing myself to be bi and I sometimes think somehow I'm making myself get hard and ejaculate while I watch gay porn (yeah I know its crazy and makes no sense) but Thats probably not right I mainly masturbate to gay porn and I've had an attraction the male body ever since i was six I used to stare at the men in the magazines. Then I think I may be gay since I barely masturbate to lesbian porn and it takes quite a while for me to get a average ***** when watching female porn (other then this one time I got a quick one from a lesbian story) but since I am quite attracted to girls emotionally and i still can jack off to lesbian porn if i really try or wanted too, that may not be the case. Then i sometimes think I may be asexual since Im not very attracted to penises and vaginas. Yeah i know this is long I'm just confused and I'm pretty sure I have a form of OCD which is why im assuming things that make no sense (And repeatedly reassuring myself that it's not true) like thinking that the porn is not the thing thats making me hard and im somehow making myself hard on my own... If you actually read the whole thing I'll give you a thumbs up :) I hope one of you guys can anwser my question D: Should I come out fully should i stay in the closet or should I just come out to my close friends or the ones I can trust my secret with. So confused.....
