A lot of porn now shows ass to mouth. I have never done this and probably never will, I'm not even sure I would ever want to. I enjoy having anal sex occasionally with my sub. I am just curious if this is becoming something girls really do and what steps do you take prior to make sure its safe???
It's called rimming, and I know a few men who love it, both giving and receiving. I've never done it myself, but with the proper precautions taken, I could see the appeal...
It also includes sucking a cock that's been in your own ass, taking the cock (or even a toy) from your ass to your mouth. It's nasty, but some people love nasty. C'est la vie.
I'll eat me, I'll eat you, BUT I won't eat poo!
