Hi There!
Well, what should I say. Sex before marriage is OK - provided you agree to have sex because you want to have sex - not because your partner wants to.
As long as you feel like it, and both of you wants to, it's OK. As a matter of fact, the Bible don't even say you can't. Sex before marriage is mentioned 3 times in the Bible, and the "punishment" was that the guy had to marry the girl if caught.
But remember to protect yourself! One thing is getting pregnant. You won't die (probably) of that. But getting HIV might kill you.
