My (27f) boyfriend (28m) gets irritated when I’m not in the mood. How do i handle this in a healthy way?

Basically the title. We've been together for 2 years, lived together for 1 year; he and I have been at this issue for a while. Before we moved in together, we would meet up once a week, which was pretty torturous. We both wanted intimacy more than once a week. When we first moved in things were great, but I started to notice red flags right away. We've worked through those, and he has shown some improvement, but the one issue still remains. I've found out that he wants to be intimate every day, sometimes up to 3 times a day. I would prefer a few times a week, although I do often want it multiple days in a row.

If I reject his advances he instantly gets noticeably irritated- physically, mentally, and emotionally. Doesn't laugh as much, won't look at me as much, and he gets short-tempered. He tells me taking care of it himself doesn't suffice. I told him the pressure to keep things civil has resulted in me getting intimate just to keep him happy, which he wasn't happy to hear because he wants to do it with me if I want too. I told him his constant negative reaction puts pressure on me, when a simple "Oh okay babe, no problem" attitude would be helpful. He says he should be able to be disappointed in the fact that he's being rejected from the person he loves and is attracted too, which I do kind of get, but I still think his reactions towards me are uncalled for.

We got into it again tonight. It was almost our bedtime and I still had to walk my dog, which he knew he ran out of time to try his advances again (after I told him I wasn't feeling up to it today for the first time in a handful of days). He said something like, "why is everything about work?" in a disappointed tone; I tried asking him what he meant, if I upset him (his tone indicated I did), etc. He kind of raised his voice at me and said "you're the one bothering me!" I walked out of the house with my dog to walk. I came back 30 minutes later and he was sleeping.

How should I handle this in a healthy way?

TL;DR: My boyfriend gets visibly upset when I reject his sexual advances even though we are intimate often, I do not know how to handle this.
