No idea if this is the right place but i'm 15 and pretty sure I might be Bi

I know puberty and everything can cause feelings like this and i'm not sure if this is a phase and I know ill feel like an idiot for posting this. But i've recently started falling for one of my friends and have met some guys online and stuff but I feel like i'm not 100% certain I am.I'm not sure if I should come out to my friends because while some will be fine with it, I know many jokes etc. will ensue and i'll probably get made fun of. And If I did come out im not sure how to or when to or what to say or anything. Or if being bi is even worth making a big deal about coming out? No idea.Sorry if this reads like crap but i'm typing this quick so I can get it over with.TL;DR: Im 15, I think im bi, like one of my friends and dont know if I should come out
