Am I a bad person?

My boyfriend is a good person. In fact he’s one of the nicest men I have ever dated. We actually have a lot of interests in common but I feel like we don’t get each other’s humor and that is such a bummer to me. Whenever he tries to make me laugh it’s actually kind of cringey lol and not funny. He’s also a bit clingy and corny. I really want to fall back in love with him but I’m not sure how. The only thing I enjoy 200% is the sex. The sex is amazing, I’ve never had such good sex and I can’t even imagine having sex with anyone else. He knows exactly what I like and no has ever pleasured me the way does. I feel like sometimes that is the only reason I am with him. Is this wrong?
