I always prefer to deal directly with the SP when possible. Especially because I prefer longer appointments of at least 2hrs.
For practical purposes - I'll end up paying somewhat less money, and she'll end up making a little more money vs. agency.
If her typical agency rate is 300$/hr, lady might make 225$ & the agency will take 75$. If I pay the lady directly, we'll usually agree to something in between & it all goes to her.
Second, communication is easier. Important examples:
If she's in a bad mood or not up to it on that particular day(maybe she's sick, maybe her cat died, maybe she just doesn't want to... It's all good, just don't bring bad vibes to the session) I'd much rather she cancel entirely vs. get terrible service.
If she wants to know what to wear in case I plan to go out with her.
I really hate when an SP wears heavy perfume because I have allergies & always try to tell her to just wear some light perfume, if any at all.

All things I do not rely on the agency to relay to an SP. There are more things as well, like maybe SP prefers I'm clean shaved - I wouldn't trust the agency to transmit that request to me.
So many examples!
I'm paying a lot lol & want to insure we both have the best time possible.
