I have been visiting the "low mileage" spas like Allure/SRM for over a decade now. Not once has the kitty been off limits to touching/massaging.
Flirt, i would classify as "medium mileage". DFK/DATY is widely available. Management frowns at BJ/FS and girls have been let go for the same.
Seduction and Perla chain are "high mileage" incall alternatives. BJ/FS is commonly available.
Pick your comfort level and enjoy!
