When is it gonna feel good?

So I met this new guy and I'm totally in love. He is sweet ,funny, and a total gentleman not to mention he is extremely attractive but that's beside the point. We had sex the other day and I found out that his dick was hugeeeee. It was so big it hurt so bad I could not let him finish. We tried again but it still hurt too much. I've had sex before, what's going on here? When is going to feel good?
