Sexually frustrated

So I’ve been with my boyfriend for 4 months now. At first the sex was every few days! Which was awesome, I love that kind of schedule. But lately I’m lucky if it’s once a week. I’ve told him a few times how it’s made me feel, and I can see he kind of tries to make an effort, but it’s only when I mention something.

I tried the talking it out and giving it some time approach. I’ve thought maybe he’s too stressed, and also given that some time. Now I took the direct approach and I feel like I just got my feelings hurt. He basically said it’s not his job to keep me sexually satisfied, and that I frustrate myself.

At this point I’m just wondering whose job it is, because I’m tired of masturbating. And I’m sorry, but when I wanna suck a dick, I’m just not gonna go out and find another dude I want my boyfriend. I just don’t think he works like a normal man.
