I don't know what to do anymore

I think my boyfriend is getting tired of me. We've been together for 2 years straight and we've had some ups and downs, but we always bounce back and we're a happy couple. We hardly fight, unless it's about sex. I'm always in the mood and we argue about it or I get upset because I will get dressed up sexy and he doesn't do anything. Eventually we just end up having sex and I feel like he just does it to shut me up. I need advice on what to do. I have given him his space, and I'll talk about it with him and he tells me he loves me. But idk what to do. Any advice?
