What in the world is a "Tossed Salad"???

"Tossed salad" is a slang term for using your tongue on
your partners anus.  It has also been referred to as
"Rimming."

If a woman’s partner uses his/her tongue on her anus
and then her vagina, then there is the possibility that
anal bacteria could be transmitted and cause a serious
vaginal infection and cystitis. If you are going to
practice any type of sex, practice safer sex and safer
oral sex. 

For safer oral sex using your mouth and tongue, cover
the area with a dental dam or some kitchen plastic wrap.
When practicing unsafe oral sex you could also run the
risk of a stomach infection or a sexually transmitted
disease (STD).
