How can me and my bf have sex (secretly)? I got caught sneaking him in last night so he is not allowed over, and I'm not allowed to drive, so how can we have sex?

Technically, the answers above are right - you are too young if you're having to sneak behind your parents' back. But from my experience as an ex-teenager, there's a good chance you won't take people's warnings about that kind of stuff too seriously.

If this is the case, then I'd suggest at least finding somewhere safe and private: A friend's house, a hotel room... It'd be a good idea to at least tell a trusted friend where your are, in case of emergencies.

I'd also strongly urge you to use protection.

Things can stop being fun very quickly if you end up with an unexpected pregnancy or an STI.

But yeah, overall, you should definitely wait until you don't have to worry about sneaking around.
