Need some advice

so my boyfriend and I have been together close to 2 years and lately he only seems interested in sex?

Like yesterday I got off from my 3rd shift job and didn’t really sleep during the day because today I had to work 1st shift and he knew that and knew I was really tired.

I told him when I saw him that I would probably fall asleep (a very common occurrence with my schedule and he’s usually pretty okay with it) but last night I was laying next to him and he’s kissing me. No big deal.

Then he decided to start reaching down my pants which he only does when HE wants sex. I told him no I’m too tired and he started pouting and his mood shifted completely.

How do I tell him that I feel like sometimes he’s only interested in having sex? It’s to the point where sometimes I don’t want to see him because I don’t like telling him no.

We’re moving in together soon and he seems to only be excited because of “24/7 sex”.

I really need to tell him about this but I don’t know how and I don’t want him getting mad at me
