I just don't understand him

Right where do i being, im only 18 years old, and had really bad relationships in the past, ive got a new boufriend who is my age for once, he's good looking and i thought i wouldnt find a guy like him. I meet him in the pub one night and now he's my boyfriend since sunday. He really nice and everything and he already wants sex. Ok yer ive done it before but with a new guy it hard to just do it. Im really confused he dont understand why and he's worried about me, yes ive had problems like i got pregnant and miscarried and stuff but when its a new guy its hard. i just need help and what he's thinking and everything, im worried that he's going to break up with me and he's telling me he's not going to. What do i do? please help

If he's going to break up with you because you won't have sex, then break up with him first. Seriously, sex should be the most natural thing and if you're not ready for it, then don't do it. Any partner worth their salt wouldn't force the issue. The only way to find out what he's thinking is to ask him. I realise if you've had bad relationships in the past that it's probably hard for you to do, and even harder to accept what folks say. But you can't blame this new boyfriend for your past troubles. That's not fair. Hope it works out for you. x
