I stopped worrying about notches on my belt long ago. These days, I seek something more substantial in my encounters. and as such, if it is a young lady I have not already met at a meet n greet or other social interaction, I pretty much insist on a brief meet n greet before I am willing to commit to a session. If she declines, respect the boundaries, and move on. If she accepts, that's a point in her favor AFAIAC.
Ladies who offer superlative services and expect to see upwards of $600 per hour should be willing to spend a few minutes to reassure the occasional new client who wants chemistry as much as he wants to fuck pussy.
Many ladies do include a social time only aspect to their menu, and its usually a very reasonable balance. Pool dates, social or dinner only encounters, they are out there.
It's a two way street. Some ladies don't really give a shit one way or the other, and go through the motions whether they are $300 or $600 an hour. To them, the guy is just a job, just another stop on the way to the Bank. Others seek to establish a rapport, and develop regular clientele, maybe even a benefactor or two.Those are the ladies who are willing to spend a few minutes of casual time off the clock in order to reinforce the potential of a long term relationship. It's a business model that does work. Just ask Angel Girl, my ATF of ten years.
No tj_tj, I do not think it is rude or inappropriate, nor do I think you make an ass of yourself by asking.
But don't expect too many positive responses, more than likely you will receive a few rude ones. Don't be dissuaded though. There are real gems out there ready eager willing and waiting to make you a happy camper. I am not VIP at present or I'd send a few recommendations your way. Good Luck.
