I am a big fan of rimming and being rimmed. However, it depends on cleanliness, obviously. This is one reason why I prefer seeing "real life" girls who come to the session after work/ uni and a shower, and you have them for the night. I wouldn't want to rim any girl at a party, or in Soho. Odd to discover, this late in life, that I like sticking my tongue up girls' arses. However, if there was even a hint of, well, shit, I wouldn't be interested. Happened once: instant turn off.
