I had this at 20, for medical reasons as described by others. If NHS didn't do it I was going to do it myself. I used to cover them in bloody cling film and vaseline out of desperation to not have bleeding calluses, problems started at 5 years old. Had to go to shop changing rooms for relief. My mum had to cut my knickers off with nail scissors at 17 because they were completely stuck. Poked out over swimsuits..
Horrendously painful operation and recovery that I wouldn't wish on any woman, left me traumatised, but it was 100% medically necessary.
Unfortunately I find every time I go for a smear or internal (very frequent as have dozens of problems downstairs) I get an 'oh, whats wrong with it? Did you buy yourself a designer vagina then?' from trained HCPs.
Waiting on therapy to come to terms with the fact I had to have it done, wasnt an option not to. At 26 I still haven't ever had sex and frankly the thought of a man seeing it terrifies me. A doctor called me a stupid vain silly girl once, what would a man think?
