It sounds like you had a lot of disappointing experiences. I'm sorry to hear that. I honestly feel badly for clients/subs who have a series of bad experiences. Because it's a lot of money to spend on lackluster sessions.

If you've been doing with for 20 years I'm going to assume you know how to figure out who might be a good match for you, how to consider how a Domme presents herself, how to do research and look for testimonials or referrals. So, assuming you did this...I don't know why you've had so many duds in a row. I don't know if these were all younger and/or inexperienced Dommes or all trained by the same one or two people, or what.

Just looking at the pro scene, like any other profession, if you think about statistics then imagine a Bell curve. You can assume that most people in that profession are average, with some on the left side of the curve who are not very good and a smaller number who are just awful; and inversely on the right side, some who are great, with a smaller number who are outstanding. Once you realize this, you then have to overlap what you're looking for among these numbers, how fussy/picky/specific you are about the Domme as a whole, and find out who the above average are and if you're willing to travel and pay for to see them (as none of those who are a truly good match for you may be in your area).

I know you're discouraged, I would be, too, but I'm sure there are Dommes out there who I bet you'd have chemistry with.
