Sounds like a thread starter from auto-censored
There are three pleasures:
a) the pleasure of licking her cunt.
b) the pleasure of enjoying her excitement
c) the pleasure of learning how to do it
An experienced and articulate prostitute might be able to give some advice on (c) but it is unlikely. Mostly they can just tell you what they like, and the financial conflict of interest means their brain is fucked even on that one. The conflict of interest means any observations on (b) are subject to excessive fakery. A genuine desire on the part of the inexperienced male is key to learning though, and actually bringing oneself to ask may pass a psychological barrier in just feeling comfortable about it. I asked the second woman I ever fucked to teach me how to make love (in so many words). I asked the first prossie I fucked to show me how a woman likes to be masturbated (in so many words, on about the 3rd meeting). Neither of them were particularly helpful on technique, but it was a psychological threshhold. You'll get more actual information
from books or from talking to a close female friend.
Which leaves us the main one, (a). Fluffies find pleasing selfishness hard. Most prostitutes wil genuinely feel more turned on if they are paid more or think they are getting paid more, which is fuck all use tbh. But you can have different parts of your brain in gear at once. i)If you can imagine an outside observer, how would he/she rate your performance? ii)If you imagine her when she is not working, how would she honestly think and feel about your 'performance?' Honestly? If she's good at her job, she will be able to switch off from the fact that you are a bald fat old twat with so much money that you can fling it at a prostitute and she will have a fantasy inside her head to get turned on if she is for some reason 'in the mood.' Don't confuse this with anything the punter is doing. It's more a case of not doing anything to screw things up. It's nice if she has a real orgasm occasionally (are you quick and observant enough to check for signs such as post-orgasmic flushed skin, changes in nipple appearance and so on - reliable indicators if they happen but not all women display them even if they do orgasm - if not get a good textbook). If she gets turned on it is an incidental
added pleasure for you - and thinking 'you did it' is a road to ruin. The main one is iii) How do you feel about it? Can you observe your own physiological reactions and adjust accordingly? You need to keep these uppermost. If you let her (or any woman) dictate what turns you on you become her plaything. Many women, especially prostitutes, use an almost Pavlovian conditioning on their men to make them willing fluffie slaves.
In other words, the whole thread is a pointless exercise IMO. Who gives a fuck how prossies want their pussies licked? If it looks nice, tastes nice, smells nice, and you think it is disease-free or worth the nominal risk, go ahead if she lets you. She might at least adjust the fake moans to tell you which licks she finds less unpleasant than others.
Or more honest thread would be, "The art of Punting. Tell us punters whether you want £100 or £150 p.h." All responses from prossies are meaningless of course.
