Erotic+ massage: RMass/etc vs Spa

[SometimesBi]

If I hire a masseur through RMass (or similar), through their ad or communication, I can determine if the guy will offer Erotic massage or even full escort service, before choosing to hire.

What about a spa? In my past travels, I've thought about getting a massage at the hotel spa. But I haven't yet, because I fear getting a hot masseur, then being disappointed/frustrated that I only received a therapeutic massage. 

If I did go to a hotel spa ... in the United States, and find I'm getting service from a hot guy, is there recommended protocol to find out if more is available?

Given the legit aspect of the spa as a business (again, here in the US), would an "employee" masseur even be able to talk about such?

Would I be better off keeping silent, but look for opportunities to brush his groin with my hand a couple times, and guage his reaction? 

Is it even possible for a masseur in a spa setting to give an erotic or escort experience? 

So I'm looking for advice if this is even something possible that I could explore on my next trip? 

Have others had experience getting more than therapy in a spa?

If you try that you will probably be banned from the establishment, and at worst, you will face charges and possibly be arrested.  It all depends on how the masseur and his superiors will react to your advances. It is not recommended.

I would advise against.

I don’t recommend either.  That said, One time at a regular spa, I had a very hot masseur and while on my back I got an erection.  Neither of us said anything but he did spend quite a bit of effort moving my draping without touching me but in a manner to make my erection seem more obvious.   Since he did not say anything or touch me directly I did not try to advance things further.

If you go to a hotel spa, expect no extras. If you live for the thrill of a possible experience then by all means try it out, but do NOT initiate with inappropriate advancements. 
 

I’ve had a couple unexpected fun times in non-rub and tug spas and they’ve been the best. But they are at best a 10% shot.

Don’t try. It’s a different product. You’d be likely to offend the masseur, and or get banned by the establishment.

If you like him and get a sense he’d offer a different service then once your session is over you could ask him if he works as a masseur outside of the spa setting. That’s his opportunity to read your request and offer his other services (at a different location) if indeed that is something he offers. If it is in his repertoire he will understand and give you the necessary information. If he doesn’t do anything like sensual or erotic massage he’ll just say ‘no’.

I've had a couple dozen massages in Vegas hotel spas over the last 20+ years and only once did something happen, and it was back when I was young and in shape and the therapist was a kid who appeared to be straight out of massage school and looking back - I think he was just into me, horny, and in his young and stupid phase.
