couldn't find a thing other than a few ads that say the same thing as EROS.

The e-mail with no phone number is fairly common among mistresses in the BDSM scene.  The quality dominas will require a questionnaire to be filled out before a session.  Well, I say quality, with a very large amount of salt.

Send her an e-mail telling her you're interested--since she doesn't have a phone number listed, she should be monitoring e-mails.

If ya see her, write up a review!
