Escort,
purvebucks and the sites within convert pretty dang well from what I have seen.
Purve.com is long established in the market, thousands and thousands of women and men customers. Why don't you give
http://www.purvebucks.com a try and see how your traffic does.
only thing that matters is your numbers, sales, etc. Alot of times you will find that for women sites rebill much longer that normal sites out there.
