Sex problems

So I’m pretty sure I’m the only person in the world who is not enjoying sex. Every time I try it hurts so bad but sometimes I suck it up for my bf & just take it. I cried a few times because its so uncomfortable & painful. Its up to the point where I dont even wanna be touched in that way anymore now but I’m also sexually frustrated. I’m not sexually attracted to him. Btw he’s the one I lost my virginity to. Any advice on things I can try to make it work?
