I have been a Professional Dominatrix over 17 years. I do have quite a few time wasters, guys who just want to waste my time. Over the years I have learned pretty early in the screening process if they are serious or not. When I screen, I ask how old they are, if they are just over 21, I do ask for an Id, but usually my age range to see subs is 25 and up. I ask what their occupation is, I ask what their interests are, clarify that I am a Professional Dominatrix, not an escort. Yes, there is a huge difference. Ask if they have any physical limitations/Medical Conditions. I then ask for a deposit. 99% of the time, if a sub sends a deposit, they are serious. I have had them not show, cancel/reschedule their session, in a reasonable amount of time, the sub may reschedule their session. If they can’t send a deposit, I give them 1 chance to bring cash, if they don’t show up, I will black list them and never agree to see them again, unless they pay deposit. My time and their time are both very valuable.
