In France, I use LadyXena (which is very local to Paris), MassageRepublic (which is international but not for the US), and Tryst (which is worth it for the occasional American traveler). However, I spend all my energy trying to get my website SEO ranking high. So. Much. Work. I miss just paying for ads and the occasional photoshoot. The loss of BackPage has made traveling for work near impossible.

So Google "Femdom" or "Domina" and the city or activity you are seeking. It's annoying, but the evolution isn't bad because I still remember paying $500-$1000 a month for print ads.
