@pecslover I have done what you want to do, and I regretted it. I would not recommend using any depilatory around your anus. You will end up with chemical burns on delicate mucosa down there.

Instead, I recommend that if you live in or near a major metropolitan area, you go to one of the guys who do waxing and shaving of men's privates. It's not cheap, but you will be nice and smooth around your hole afterwards, and while it hurts a little to have the hairs pulled out down there around your anus and on your taint, it's not as bad as coping with chemical burns for days afterwards.

Good luck!
