We all have different experiences as providers and I will jus tell you mine.
Men in their 20's and 30's are more likely to:
Ask endless questions, and never book appointments
Cancel appointments/no show no call to appointments (This is probably the biggest issue)
Be related to Law enforcement
Be more sexually demanding
negotiate rates
Try their best to convert a provider into a girlfriend.
Because of these unfair stigma's, yes you are right, it is a little more difficult. So here is what you can do.
Be very lengthy and detailed in your initial communication with the provider. Review her website and find out as much as you possibly can about her and potential time with her. At any age, this automatically gets my attention.
Pre-pay/offer a deposit. Guaranteed, this would eliminate any uneasy on the providers side.
And lastly, if she gives you a hard time despite following the above, she wouldn't be a gal you would enjoy seeing anyway:-
