I try to always see the same girl so that I become a regular (means I avoid touring WLs and those advertising 'last few days').
I currently have a regular - while she does not really provide anything 'extra' (because she advertised all the things I was looking for), now that we know each other, she trusts me not to try anything she is uncomfortable with, and I trust her not to bait and switch or cut short the time, etc., so now we have unbelievably relaxed, comfortable sensual sessions.
I have never been into looking for something extra for free, but having a working lady relaxed and being totally with me 'in the moment' is priceless - in some ways much more than my ex ever was !
That's why I go back to the same ladies.
