I love P4.
It used to be by invitation only when it started around 2004 as Private Connections.
Nurse Dennis And CK verified me in to it and I am still a member there. P4 is the Easiest platform to choose company, communicate, verify and keep in touch.
I can see if my male partners are still active, because there is a history of appointment requests and OK's. Checking on a gent behavior BCD, despite OK given, can be done without asking a guy for anything, just click on the provider who gave OK and send pm to her with request for more information and all necessary info is already visible to her: when she saw that guy, who he is, and how will she remember him.
There are no discussions on P4 like this one. Just a list of all available ladies, donations, pictures, basic service description and a way to contact a provider. That's it. Perfect.
