Is sex supposed to be this way?

Is it normal for your partner to always want sex? I mean like he talks about it everyday. I don’t really like sex because I honestly don’t think it’s that good. I don’t really enjoy it and it feels like a chore to me. He on the other hand is obsessed. He touches my butt any chance he gets, talks dirty all the time, insinuates it, etc. I’ve already told him how annoying it is. We can’t even have a normal conversation without him making a sexual remark. I’m starting to get the ICK from him. He’s on the smaller side so I don’t get much pleasure, like he does. He can also be such a jerk to me too which throws me off unless he knows he’s gonna get some that night. He just sounds so thirsty to me. Idk thoughts?
