This is true. I have been seeing the same 2 ladies for over 7 years and I have never said I would be a regular. We are however friends and they know I will be seeing them there is no need to even bring this up. I am very lucky to have both these gorgeous young ladies in my life they are both amazing women.. If someone wants to be your regular, he just will come back. I've had many clients come back 3-5-6-7-10 times even more and they never promised anything. They just booked again.
If someone offered an arrangement that was worth it for me, I'd accept it probably, but I wouldn't give up escorting entirely... I'd probably just see less clients.. but I'd probably be trying to invest in other things eventually if I saw the gentleman was faithful to his promise
As far as SB arrangement. The whole point of seeing an SP is not to have commitments or things that you have to abide by on a weekly or monthly basis or whatever. For me SB arrangements are ridiculous, just a way for both to make believe that one is not a prostitute and the other is not a client and for both to somehow feel better and superior to other SW and clients.
It is enough to be able to enjoy each others company and to know that you will be treated with kindness and respect on both sides.
