Cherry Vanilla

A term in the swinger (non-monogomous lifestyle) for a person (or couple) who appear to be sexually open or adventurous, but doesn't (yet) actually engage in non-traditional sexual activities.

It's derived from the term "vanilla" which is used to describe a mainstream person who isn't in the swinger (or alt/kink) lifestyle.

Mary is such a hottie...do you think she'd be down for a threesome? No? Too bad...I guess she's a cherry vanilla.
