The ratio of females of any role seeking vs males of any role seeking is so high especially online. So females can be more selective and have more to choose from. As far as pay. Well it’s a by product of desperation. Guys who want a female so badly are willing to pay to get front of line privileges. This has over times formed a habit of females who know that guys who are desperate will pay. Most of the fin dommes, sugar baby, mistresses seeking money aren’t really all that experienced in kink and they just basically halfasss things and the guys still pay cuz any attention is better than no attention.
now on the flip side. Yes there are pro dommes/doms. They are very experienced and they charge for their time. This is basically equal to sex workers like escorts or strippers. Again it’s all about what one is willing to pay for, Essentially it’s supply and demand. If no one paid anyone for these type services then there would be fewer that would be charging for it.
I personally feel that the money aspect removes the genuine real connection and it now becomes business but everyone is entitled to their opinions.
If one is patient there are plenty of good legit non pay females on both sides of the slash out there.
