When will sex start feeling good?

I’m 19 and I’ve been dating my boyfriend for 7 months now, we’ve had sex 10 times and I didn’t feel any pleasure at all any of those times. I was a virgin before him but he had been with people before me. When will it start feeling good?

UPDATE:

We’ve tried a lot of positions, me on top, doggy, reverse cowgirl or whatever and pretty much every position you could think of. Also, fingering doesn’t feel good for me, he’s too rough sometimes and can’t seem to get it when I tell him it’s hurting. He goes slow and then fast and sometimes just really fast and sometimes just slow.
