I pay a WG so that she will provide me with a service, not the other way around. By allowing me to lick her pussy she is providing me with a service that I have paid for and chosen to engage in for my own reasons, ie; I get off from it. What she gets from it is her concern and not mine. To say to myself that I genuinely care whether or not the prossie gets genuine enjoyment out of it, is to delude and lie to myself that I give a shit about that, which I honestly do not. In normal everyday life, hot girls you don't even know don't normally just let you walk up to them and then take off their clothes for you and then allow you to lick their pussies, and then thank you and offer you a 'discount' for doing that generous favour to them.
If only reality worked like that though, add in penetrative sex, a blowie and kissing, and they'd be no need for me to ever have to pay prostitutes for sex.
Don't get me wrong though, a punt tends to flow better for me if the sex feels more natural and relaxed, and to me that does mean involving things like RO or fingering and kissing. But it's all just a superficial act to me. The better GFE providers do a very good job of making it more convincing and enjoyable. But like I say, whether they actually enjoy it is irrelevant to me, and I certainly do not care for a thanks from them, whether it be in the form of a discount or preferential service. I expect good service from a good service provider, as long as I'm clean, on time, respectful and paying the right fee, whatever my performance, looks or personality is like beyond than, shouldn't come into the equation of the effort a good service provider puts into giving me a good service. That's not to say that I don't think preferential treatment happens, prossies are human of course, but just that to me it is irrelevant to my interests.
