Anyone had prostate milking? Good Locations?

Anyone had prostate milking? Good Locations?
Heard a lot about them and looking for a really good one

Have enjoyed a couple of times with some private’s but I’m certain that almost all of the parlours would offer this as an extra if you ask your ml respectfully

Yea I have seen a lot advertise, but it's more than just some boiler prodding around in there 😂
