Painful sex

Mack

I’ve always had this problem from the very first time which was when I was 18 I’m now 21 and nothing ever feels good during intercourse sometimes it bleeds even when me and my boyfriend use lube it’s painful on the inside and out it burns afterwards most of the time I have to stop completely in the middle because it starts to hurt and I almost don’t feel anything kinda numb if you will I’ve been to the gyn in the past and they thought they could see cysts so they put me on birth control that was 4 years ago but I’ve gone back since and there’s no sign of anything through the external and internal ultrasound. Anyone got any ideas as to what could be going on
