I always ask my regulars providers questions that im curious about and one of the most common things i hear are things like "do you want to cum? Do you want a bj/hj?"
Most of them say something to this effect, respectfully so "dude, I dont have to rely on clients for a release, you're not doing us a favor, everything just depends on the vibe".
Many of them will say that alot of clients dont brush their teeth or aren't freshly showered. How are they supposed to be turned on when basic hygiene isn't met. We wont always be a match with the provider we pick, however I will say with time some will warm up to you, some won't.
Just like in the dating world, you wont always be a match. I appreciate the provider’s I've hired who aren't much into me but still do the deed with enthusiasm and politeness.
You can't expect everyone you're into to be into you. And that's okay. Its a hit or miss. I have several regulars amd I'm thankful for them, no surprises, no awkwardness.
Almost exclusively they have all told me it doesn't matter how the client looks but more important is how they're treated and how their hygiene is.
In conclusion, I believe for best possible outcome I would say be as accommodating and respectful as possible. Be showered with your teeth brushed right before and be respectful of boundaries and that's as sure as you can be that you'll get the outcome you're looking for.
