Girls, girls, god

Ok fellas, im going to sound like a 5 year old for this but o well.

Look evry time my girl wants to give me a b.j. I say no. I don't know why! I guess that I feel like god is going to send me straight to hell for it. Or if thats not it then I don't...

know what it is? Im straight, 15, shes felt it, I've felt her down under, I just dont know! Help me!!!

ok, first off...I think its a sin.im not for possitive though.. and its not really the best thing to do.. and if she does, its better not to kiss her afterwards. bc look at it this way... if she gives you a b.j, then kisses you, you practically just kissed yourself. and thats just screwed up...
if God is telling you not to do something, its better not to ignore him.
