um ... it seemed to be a very specific problem on a PSYCHOLOGICAL basis, which, if I'm not mistaken, was called "vaginismus" with its sonorous nonsense. excessive tightening of the vaginal muscle rings, which results in painful and unpleasant / and in some cases - impossible / sexual intercourse for the woman .... so boy, most likely it's all in your head. unfortunately I can't advise you where to look for help, but whoever seeks - finds :) success
