Ok I'm 14 in a half and I don't know if this is puberty or not. Please help I need to know!!!!!?

Curiosity, even experimentation, is perfectly normal and it's way too early to make conclusions about your sexuality. There have been a number of studies on this and they're all clear on one thing: to be gay or even bi you have to have an actual sexual or emotional relationship with a guy. Just checking out another dude's package or even jerking together or casual playing around is not enough.
