I'm gonna disagree with a lot of what has been said so far that straight up, genital electrolysis might be the most painful thing I've ever done. Well, maybe not in the long run as much as the long recoveries of breast augmentation and SRS...but it was VERY painful. I used a prescription numbing cream but it barely worked. And luckily, I didn't have to get electro on the face so that might be worse (I had laser hair removal for my face instead).
Also, some weird thing happened where I think more than enough hair was removed, because now part of my labia are completely hairless in places that they shouldn't be. If scraping the hair follicles off really works, I say do that (though I have heard that it can still grow back that way...)
