Injured vagina

So a few months ago my boyfriend went down on me. He had a vaccum air tight grip but i felt like it was extremely painful. He never did it like that before. I tried to let him know by releasing his grip but he kept going back to the same thing. Fast forward today, when I masturbate I cant feel any kind of sensation. Not even an orgasm. I feel broken now. I don't feel normal. Can this be reversed? Did he damage some nerves down there? Sorry for being a bit graphic, I just need you guys to understand the pain I'm going through
