My fiancé isn't a virgin but....

I am, and I have decided to wait until marriage(we are getting married on the 22nd). We are 22 and he had a baby with someone when he was 17. Anyway, I knew that even before we started dating. My point is, I'm scared that since he's a little more experienced, he won't take it slow or anything and that he'll have someone to compare me too. I have really bad anxiety about stuff like this, any advice?
