Anal Desensitizer : eBay Guides

I'm no expert but...

ANAL DESENSITIZERS ARE BAD

The pain of doing anal sex is natural, and with practice and care it will diminuish. If you desensitize with the products sold here (or get drunk), the pain won't tell you when you've had enough.

Pain is a natural responce, don't numb it or you are putting yourself in SERIOUS DANGER.  You can permanently tear your anus.
