Speaking with my own experiences: which is quite a lot for RnT but rather limited when it comes to FS!
Firstly with FS: since I don’t go often so hardly ever see any WL more than once (except Milo from 5 Star and that’s long time ago !) therefore , whatever “routines” they did to me was fresh, unique and quite enjoyable! And I wouldn’t cum close to get bored as the same deeds were never repeated ! Every FS to me is an adventure and excitement and exploration of the female bodies and broaden my sexual horizons, so all good ! Besides , as I almost always only see busty girls, so if all fails, there’s always the Spanish to fall back on.
Now for RnT: this is more complicated and for me it could basically boiled down to two situations : the one hour session and the 30 min quickies !!
There were times when my chronic back problems were playing up, massage was a necessity and only the one hour or longer session will do. And I would have gone to legit shops to get it fixed !
Then of course, the horny nature took over and a release in the end became equally important so the search for the therapeutic MLs began: many of them were at Zanadu and old Chequers or Babylon. Then I found this forum and 501 Newtown was like a gold mine. The rest was really just history : so many genuinely skillful massage masters such as Coco, Lisa (HK), Candy, Yuki, Cherry (not the 🍒) Sue and Nina.
And yes, most of them have a set routines which can be modified if my needs are varying. But they gone through their own way so that your whole body is covered including between your legs........ lol.
Then the 30 min quickies - now that’s just anything goes and every man for himself and definitely YMMV !
