Sorry hun ...... I
genuinely didn't mean to be offensive at all.
You asked for McGinn patients and I'm not one so I was just explaining why I was answering anyway, then kept my post brief (for once) by just listing my points.
When I was in for my op, there was a girl in with a problem and I could overhear the surgeons quiet conversation with her after her op. Her problem was internal hair. Dilating and sex pull some of the hairs out and they get tangled with other rooted hairs and gunked up. They compact and become a tight wad like a wire pan-scrubber, build up and build up leading to discomfort, loss of depth, inflamation and infection.
My electrologist has been treating MTF's for 30 years and has been approached many times by girls with internal hair problems but has been unable to help. Sometimes the surgeons themselves have been a bit blase about genital hair removal and said Oh don't worry about that, but if it does become a problem then it is recurrent and practically impossible to treat by any current means.
I had very little money, even though the NHS were doing my op (simple inversion) at no cost to me. There was no way that I was going to take that risk as when I looked at my situation critically, I had hair fully halfway down the shaft. The clitoral area also needs some clearing.
If your op involves a scrotal flap then scrotal hair is a big problem as it will be right at the deepest part of the vagina.
Don't chance it, it just ain't worth it.
Again, sorry if my short reply seemed snappy, that was not my intention.
