I too would like to stay longer with an attractive lady but I am a real cheapskate. So the amount of time I spend is based on the asking rate, the class of lady and whether I feel a geniune connection. I make enough money that I could afford to pay up to $1000 for an hour but would rarely pay more than $360 for a one hour visit.
Most of the women who charge above that price, while a few are absolutely beautiful, intelligent and worth the asking price, I avoid for the simple reason that I am intimidated and worry I cannot perform.
