Rimming definitely falls into the "kinky" catagory; I mean, we're talking about where your poop comes out.

I have to admit however, the few times I've found a provider to do it, it was heaven on earth.

There are providers who do it, and I suspect even like it, so keep searching.  Of course, you will both want to do a lot of cleaning up before hand, and keep some Listerine handy.

i had a girlfriend do this to me for the first time a while ago and while a little concerned about what it would mean if i enjoyed it, i found that i really enjoyed it.  

i have a woman that i see locally on occasion who truly enjoys giving and receiving.  she really, REALLY gets into it and loves when i reciprocate.  i've also found that i enjoy doing it to her, and other women.  they generally respond quite well to it.

Isn't hepatitis an issue?  One should have all their shots before rimming, right?

I would do it (as a provider), but only if the guy were comfortable with me cleaning his ass (with rubbing alcohol followed by plenty of soapy water) beforehand. Mood killer or not -- I've seen guys that don't even bother to brush their teeth beforehand (no, eating an altoid is not the same) -- who knows how well they clean their ass?
