I hear you DM. However I, like so many others, am fully prepared and very happy to pay for the privilege of going down on a hot girl's pussy. And when it's a smoothly shaved one it's so much better imo.
I also fully appreciate that the hot wg I'm lusting after is there in a purely professional capacity; isn't really after my company, body or my cock and probably isn't expecting to get much out of the encounter aside from a chunk of cash. Yes, of course, she should be fully prepared to invest enthusiasm and effort into putting on a convincing performance for me if she's keen to build a good rep and/or have me as a repeat client.
So if, by me shaving my crown jewels, it makes it that bit less nasty for the girl to go down on me then I'm happy to do that if it results in me getting a better bj. I appreciate there's no guarantee that the outcome will be any different had I not shaved. But my simple logic says it's likely to improve my chances. That's all
