Domina M, I get the feeling that the person who contacted you may wanted to engage in a few emails and was not serious about having a session.

I'm not in the market, but if I found a Mistress who intrigued me since we seem to have the same tastes, I'd do the following: check to see if she has a website; check if she has social media & for how long; Google her name to see if reviews and/or red flags appear; and visit sites like this and see what has been posted about her, or post if anyone has served her. And check whether the deposit is required, or within your budget to lose. And, really consider if you are willing to provide your ID to a complete stranger.

This type of discussion reminds how I ever took a chance answering New York Magazine's now defunct "Role Play" personal ads to contact a Mistress in the '90s, and how they took a chance posting the ads. Two or three lines of copy, name and a phone number. The phone calls were an interesting dance too. You had to be respectful, yet get some info about the Mistress and her repertoire. The Mistress has to provide some info, entice the sub and figure out if you were legit, NYPD or an axe murderer all in a three minute or so phone call.

To echo Chi61's comment, my hard earned advice to fellow subs is, "Think with the head on your shoulders, and NOT the one between your legs."
