I wouldn't go about telling you wonderful ladies how to run your business, but the term "Fire Crotch" is not one I would pick for your advertisement. The connotations this brings up are not of a pleasurable experience.  This coming from a man who once put Icy/Hot on a groin pull.

"We here at Roman Meal, just thought you'd like to know."

Genius!  I didn't make the connection regarding hair color. Still - I don't ever want a fire down below, nor do I want to be with a lady who has a fire down below and will end up giving me a fire down below.  In fact, I generally avoid a fire anywhere lol - except maybe in my heart.
