"Ewww Gross! No way!" ;-T
Heh!
It's not my cup of tea, to be the rimmer or rimmee. I've never tried it, but it is one of those things that I just know I wouldn't enjoy very much. If someone really wanted me to rim them, then I suppose I could do it, ensuring everything is clean first, but the thought of a slobbery tongue near my anus makes my skin crawl!
It's true that it's not as taboo as it used to be, you even hear the term on tv these days!
