Selfish sex?

I just had sex with my boyfriend of 3 years. I feel like he’s being very selfish and I feel like his toy. We had sex and once he was done, he got dressed and left. I started crying In the bathroom and he asked what was wrong. And I told him I get like I was being used for his sexual pleasure. And he said that it was because I (me) can’t feel anything during sex.

Sex doesn’t feel that great to me, it hurts and feels just like pressure. I told him there is other ways he can do to make me feel good. And he just shrugged..

What do I do? I feel worthless and used
