Any service provider, in any field, should strive to go above and beyond to make each of their clients happy. However, in the hobby, as in many fields, the client can sometimes be his own biggest obstacle to ultimate satisfaction.
If you arrive at a date with even a slight chance that you could be malodorous, sweaty, or clammy in any area of your body, please ask to take a shower. And don't just rinse off. Scrub. With soap. And rinse well. If you're not squeaky clean, don't expect to get a lot of oral attention down there.
If you give off a condescending, demanding or rude attitude, don't expect to get much love in return.
If you do things that make the provider uncomfortable (i.e., attempting to order "off the menu" items, doing things she's already told you she doesn't like, haggling regarding the donation, being rough or overly aggressive BCD, etc.) then expect to receive lackluster service, or even to be asked to leave.
Treat the session like you would any other date. If you are clean, respectful, and pay attention to nonverbal and verbal cues, and your requests are within reason, it's my opinion that the provider should focus her attention on making sure you have a great time. And remember that everyone has personal preferences and limitations that come into play. Like Viv said in Pretty Woman... "I say when, I say who..."
For me, a few specific things will always make me politely warn a client that I don't like that particular action, and will even make me stop a session if the client doesn't listen. I don't offer Greek, and absolutely hate having someone's tongue shoved inside my ear or having my face licked, so attempts at either of those will make me pull away quickly. But the quickest way to ruin a session with me is to forcefully push my head down. Resting your hand on my head or neck is fine. Gentle guiding is fine. But I have a history of neck and shoulder injuries, and other personal experiences that make that a big no-no for me. A forceful push will get one warning. Another one will end the session.
Aside from that, if it's not painful, cruel to animals, children or old people, or something you saw on "Big Dicks Inside Her Ass 11," it's all about you.
It depends. I think the best dates are the ones where there is communication before hand about likes or dislikes. Although I believe in letting things happen organically. If you are more of a pse kind of guy or sensual and passionate gfe kind of guy let the provider know. I find my BDSM sessions go wonderful because of the amount of communication before hand. I have them tell me a little bit about what they fantasize about and it makes such a difference. Something else to consider and I will give you an example. I did a 2 girl fbsm for a gent not too long ago. He had had doubles sessions that were interactive but never had he just lay on a table and have two girls tend to him and not have to do anything in return. But, if you gain gratification from pleasing the lady then I guess it wouldn't help to be all about yourself. I think you should be able to do what you like as long as you respect her boundries. I am so greatful I have only had a couple of clients that thought they were entiltled to tell me what to do, be rough, degrade and totally try to objectify me because they were suppling a donation. That was not cool at all and their is a special place for those type of clients. Luckily its only happend once or twice. I was really shocked when I first started providing to see most gents care about my pleasure as much as they care about their own. Its definately nice!
It is about me, but of course it would me much better for me if my partner wanted to please me. So, in my simple mind I say, I please you, you please me. Also, most men would get a boost to their ego if they could pleasure a woman at will, and the sight, feel and smell of a woman in orgasm has to be the greatest turn-on. Isn't that why women fake orgasms...for the sake of our fragile ego?
