[NSFW] Why do I experience pain during intercourse? (look inside)

Okay so when I have intercourse it hurts a lot when it goes in and the pain seems to never get better. Every time I do it the pain is there. I seem to never get wet and my gino can not figure out why. I’m on birth control so I don’t know if that’s stopping anything or what. I was thinking if I take muscle relaxers, it would make me loose and it would stop the pain. Anyone have any ideas on what I can do and if muscle relaxers would help….
