I haven't read all of this thread but it seems to be a popular one! It's a bit off-topic, but re "perverts" it might be entertaining to relate that that there's the other side of the fence! (BTW, although I'd love to receive massages, and also give them, it's basically not featured in my life. However ....)
I spent some months in India in 2007, and some of the time travelled with a couple I know. The male of the couple wanted to visit a "healing ashram". In fact, it's where we arranged to meet up in India. The ashram had very little spiritual focus, but was oriented - and its system actually inspired and set up by Gandhi - towards a multitude of naturopathic healing treatments, for any ailment or nothing in particular. You really did get the works, and were "busy" going from one treatment to another almost all day long. At only a few £s a day all-told including your en suite room, for Westerners it was obviously a bargain. But to the point:
One treatment all were required to receive was massage daily. It wasn't "relaxing" but very strenuous at times: the thumping of one's head and shoulders was right up to about the limit I could take.
No one told me what to wear, if anything. I don't see any point in wearing clothes if your body is supposed to be massaged, but India is considerably more puritanical than the West, so I kept my underpants on. (With different therapists to me, my friends didn't wear anything and the therapists didn't say anything about it.)
I was only there for the minimum stay of one week, and in the second half a new and more experienced therapist began work there, and took me on for massage. He was excellent. On his first day at the place, he sussed something wasn't right with the VERY young Indian who'd done me the first 3-4 days. This first massage therapist seemed only about nineteen. In my second session I was on my stomach and he pulled my pants down a bit, which seemed practical. But his hands went beneath the band as well - hmm, well I didn't know what was supposed to happen anyway, so still OK. But then his fingers just for a second went .... shall we say, "even lower". Yes, there!
In RL I'm actually a pretty placid and quiet person, so I just lay there wondering what to think of this! At the time I figured it was 50-50 whether a mistake or OK, or a naughty move. It was such a surprise, I really didn't know what to do. I decided on a "two strikes and he's out" policy i.e. he was going to get it from me at least verbally if it happened again. And it didn't.
On reflection afterwards, I believed he was seeking out gay Western males who'd pay well for "extras". But he was thankfully replaced for me anyway.
So. The moral of the story is that it may not always be clients who are the pervs!
