For gay teenagers
I'm 16 years old and I'm still not sure about my sexuality. I'm a virgin too. I guess it's something I'll have to accept if I really am bi. But I still hate it.
I was the same age as you are when I realised I was bi, and it gave me a few sleepless nights at first. I soon came to realise that as long as I was careful, and avoided the more redneck members of my school, it was no big deal. I'm currently at college in L.A. and nobody bothers about my sexuality. Don't sweat it, you are no different than anyone else, and as for what the neo-puritan brigade would tell you about being a "sinner", well, that's just their bigoted opinion. Hope this has answered a few of your questions.
