Yea, it sounds like you’ve got a medical problem. As a guy I obviously dont know first hand but I have been in a 15 year relationship that averages sex 3-4 times a week and I can pretty confidently say that putting things up there should feel good. Hell, I dont think the strap-on market would exist if it didnt. Too many lesbians doing things to eachothers holes for it all to be some mass trauma response thats turning pain into pleasure.
