Never tried receiving rimming, would like to try soon. I would like to ask your opinion and few suggestions on companions who give rimming.

You posted to Boston, too, in advance of traveling there. No one can answer how YOU will respond to the experience.

For me, it feels OK but I don't like it. I don't want to be kissing and DFKing the same mouth that has been licking my ass. If I sense the action going in that direction, I actually ask my hostess not to do it.

If rimming is new to you, I have a different recommendation. Instead of making it the raison d'etre of your selection, why not search TER Reviews for ALL of the things you are looking for -- age, hair color, MSOG, -- and include rimming (one of the data fields in the searchable database) in your criteria.

That way, if you are disappointed with the rimming experience, you still have everything else going for you.
