Vaginismus?

I just came across this term today, and I feel like it is exactly what I have. So many issues with tampons. Virgin, but no sex drive because I know it would hurt. Does anyone else have this? If so, how did you get diagnosed? There’s no way my PTSD would let me do a pelvic exam or go to the doctor, but I’m on my period right now and I can’t keep dealing with these impossible tampons and stuff. So much pain.
