Up in Canada of all places in a small town in Quebec, in fact.
I ordered up a 2 hour session and was even earned by the madam it was DIY, but the price was right ($100), so I figured what the heck, and went ahead.
The gal was not bad looking, sort of built like the proverbial brick shithouse, and I got a decent 45 minute massage. Then on the flip she handed me the bottle of lotion and I jerked off to watching her rub one out. I sort of liked it for the novelty if nothing else, but then it got better.
Then it got more interesting.
We chatted a bit and I tossed off a line, not thinking it would be taken too seriously, that I wish I could massage her. Well, she said she would like that too and before you know it, I was seated on her very ample and oily butt giving her a very sexy massage. I even thought about asking her to flip over and getting some DATY action as well as P2P action but I didn't want to overplay my hand. So I ended up coming on her ass crack and feeling like quite the lucky guy.
To top it off, she finished out the last half hour with more decent massaging.
I tossed her another 50 when we parted. She was one happy gal.
This was back in the late '90s.
So give it a shot. As Chuck Berry sang: Goes to show you never can tell.
