My first time

I had sex for the first time and it hurt a little but after like a minute it stopped hurting but I also didn't get pleasure from it. And I've done it a few times after that and I still didn't find a real pleasure from it like it just felt like nothing to me, and I really like the guy I was doing it with but having sex just wasn't what I expected it to be. What does this mean? I'm so confused if I should just keep doing it and hopefully by sometime I would feel some kind of pleasure from it?
