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.

Everybody should experience Rimming at least once!

I absolutely love to be rimmed, it feels so damn good! I have also been known to reciprocate. However, I am very picky as to whom I rim. They MUST be very clean, preferably just out of the shower and they have to be closely trimmed or shaven. Otherwise, I'll pass. I also will not allow any ass to mouth. I have spare toothbrushes and mouthwash readily available!

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?
