My boyfriend says I’m too demanding about sex

My boyfriend and I just started dating, I’ve been single for 4 years and he’s been single for 12 years. I’m 28 and he’s 35, We are very good together, he’s cute and attentive with me and shows that he cares a lot, but for the last weeks he’s been saying that I demand too much sex from him. Apparently, my sexual appetite is too much for him and he mentioned that my “demanding” is keep him from performing. I don’t know what to do, I feel like I’m pushing him to do stuff he doesn’t like, but at the same time I feel like he just doesn’t like me.

I just feel very frustrated, like, I don’t like the idea of being labeled as “insatiable”, but i have a really hard time demonstrating affection and sex is my go to move when I love someone. I just feel lost, I love him a lot, I can see a future with him but at the same time I don’t like the idea of “demanding sex”.

It’s gonna be a week now without nothing, because we tried before and he couldn’t perform. He says that he’s too stressed about pleasing me all the time and the recent changes he went through.

Am I greedy? I’m just lost. Because I wanna feel closer to him, but I want to be understanding. I just feel as if being with me is too much “work”.
