What services does the provider give for "natural french"

Natural body hair, does not shave under arms, etc.  I use urbandictionary.com to look up those terms and acronyms.

"French" is a euphemism for oral sex (as is Greek for anal, Russian for a boob job, etc) so it stands to reason that "Natural French" is colloquial for BBBJ.

Definitions are in the newbie manual at the top of the page:

Yes, and you sometimes see "untranslated", or "without translation".
