This is the problem having a "regular" in that there is a void to fill if they retire or move on in some way.
I always wanted to have 5 decent girls who gave a good service and then throw in an occasional new punt every 4 or 5 punts to try and find another regular in the expectation that one would fall off the radar at some point.
Unfortunately being picky I never had more than 3 "regulars" at the same time and all the new girls that I punted just weren't up to seeing a 2nd time so it ended up that I basically just saw the same 3 girls almost every punt then the same 2 when one went AWOL.
When both of these regulars fell off the radar at about the same time and my "Go to" parlour got shut down my punting was up shit creek.
It's never really recovered fully but now I punt about 40 times a year and class a regular as 2 or 3 times a year.
Still looking for a harem of decent regulars but alas I fear it's just a bubble
As already suggested don't punt for the sake of it but no harm in looking
