I have to agree with a couple posters who have said that a theme that includes "sex" probably isn't the best PR choice. Also bad: the word "whorehouse."
I had a flashback to the "Best Little Whorehouse in Texas" skit I was in one year. My costume included a boa and lingerie. Whoever thought it was a good idea to have a close-knit, supportive group of hookers exemplifying the bonds of sisterhood was seriously mistaken.
