Its an attempt to be all things to all people. A lot of guys, like me, who like GFE do not see PSE girls, mainly because we like DATY, and who wants to stick their tongue into a hole that was a creampie 20 minutes ago? Not me. So what they are offering is a full GFE Kgirl menu, but with a PSE option, which just means they will do CFS or BBFS, along with the usual GFE activities like DFK and BBBJ.
Many of the girls that have chosen to go publicly to BBFS (PSE) have found that its a tradeoff. The young guys that think they are immortal gravitate to girls that offer bareback, and when a girl puts it on her menu, she will be very busy for awhile. The tradeoff that comes is that she will miss out on older married guys who are still fucking their wives on the side and so they don't want to risk catching anything and giving it to their wife.
The girls that go BBFS also learn that these older customers more often book more frequently, tip more often and in bigger amounts, will book multiple hours, and are more prone to becoming "regulars." The younger guys tend to not repeat much with the same girls, are always looking for the next PSE girl, don't tip as often or as much, and rarely book multiple hours, preferring instead, to see two girls for an hour each rather than one girl for two hours. So while PSE girls initially get more business from the rush to get BBFS from the "new" PSE girl, in the long run, they make less money because they lose the business from older guys that DON'T see them anymore. As many girls will tell you, once they go BBFS, its hard to take it off the menu without losing even more customers that have come to expect BBFS. Many former PSE girls have gone back to CFS only and are doing better financially than they did as bareback girls. I think because of the economics, we will continue to see PSE among Kgirls, but it will be a transitory offering. It will come onto their menu for several months to a year, and when they realize they can do better with CFS only, because its a bigger customer base with deeper pockets, it will come off their menu just as quickly. There are always exceptions, which are the small minority of girls that always have been and always will be open-menu.
