I’m 18 and we’ve been together for 3 years

I love my boyfriend and we are even planning on living together with some friends in two semesters. We have a puppy and basically see each other every day.

I’m in love with him but our sex (on my end at least) fuckin sucks lol

I love him but sometimes I just wanna have that sexual experience with someone great. Is it bad to feel this way? I’d never cheat on him, I just wish he thought of more than just himself during sex; especially considering that we’ve had multiple conversations on what I like, how to make it better, and so on and so forth.

What should I do?

(I’m sorry if I sound like an asshole)
