Idk what my deal is

So me and my bf have been on and off for almost 4 years. I never don’t want to have sex with him. He’s been the only person to ever get me off, but sometimes the positions that get me off hurt. And others don’t work at all. It’s a long, tiring chore for both of us to get my to finish. I’m to the point now, where I don’t even get wet. I can use toys for an hour straight and I don’t even get wet. I used to get wet giving him head and now I don’t. He’s to the point where he doesn’t even want to have sex with me because it’s a chore and half the time is so painful so I just let him finish, because I don’t want to deprive him of it. It’s not his fault, but I still feel connected when we have sex. The feelings are all still there, my body is just broken. Idk if anyone has tips or advice Or tricks or similar stories so I’m not alone, that would be great.
