Isn’t this sort of Caveat Emptor? How on earth are you supposed to know if a HE will be part of your massage? The masseurs cannot advertise that that service is part of the massage. Plus, from my experience, I think the HE or “extras” are all about the connection and energy that exists between the client and the masseur. My experience with one masseur can be 100% different from someone else’s.
If you are not willing to take that risk I think you need to stay off masseurfinder and rentmasseur and visit spas instead.
