being Christian and having sex

Ok so I really don't know what to do. I am a Christian and according to the Bible we are supposed to wait for marriage to have sex. I've asked different people what they would do but I don't think any of them are Christans and I'm too scared to ask anyone at my church. I've gotten different answers like "the Bible is dated" "the Bible didn't really talk about dating so I think it's ok" and "as long as you're in love" but I'm still having an internal war and I need help.
