generally speaking, between customer and WL:
when he sees her multiple times, he starts to get bored and can't get hard.
when she sees him multiple times, she starts to have orgasms.
interseting difference.
I find that the more I see the same girl, sometimes the harder it is to get her to orgasm. You lose out on the intensity of the "stranger" fuck.
Sometimes it is possible to keep it going even for several years. I had a regular for 9 years who orgasmed like crazy everytime I saw her from the first time to the last.
With regards to men getting bored and can't get hard that is the great thing about punting, there is a new girl behind every door to get your pecker rising again.
Is it a bird, is it a plane, no its Punterman. Always seeking out good value bbbj, DFK, DATY for $150 hr in the Western Sydney brothels.
The trick with a regular is not to see her too often, that extends the "honeymoon" period!
I guess it is quite common for sex to wane :@ alas punting a healthy mix of girls of all nationality might be a thing too
