You won't be their first noob, and they didn't get to where you'd pick 'em by turning noobs off. Trust that the good places—the ones most reviewed in the Massage Forums—understand they're in the business of women pleasing men. Even noobies. There are a few places that consistantly disappoint; focus more on weeding them out, than on finding the Number One Spot we've all been looking for.
You'll be as well turned out as you would be say for a decent meal out. Howver it's not unwise to carry a minimum amount of cash and ID. You'll walk in—well maybe you'll be buzzed in thru a locked door—and you'll go up to the greeter/receptionist with a pleasant smile and tell her you're there for a massage. She'll likely determine for how long and collect a door fee based on time. This may happen at the desk or after she's shown you to a room. Nothing wrong with asking to see the room before committing if it matters to you. Likewise nothing wrong w/ asking to see the available MPA's, and it's best to make clear you'd like to pick before you're taken to the room. Although some spas do the show and tell there, some do it in the front. Before the parade would be the the appropriate time to mention 'special' sessions, as not all MPAs do all of them—shower massages that leave their hair wet f'rinstance. But you can be confident, at a better MP, that whoever's on deck will be accomplished and attractive.
In the room and girl selected, you undress and shower, making special efforts in places that smell or that you want her to pay attention to. Don't worry if the shower's down the hall if you've chosen a more budget place; the towel you wrap with will be clean and keep you decent. As if by magic she'll arrive just as you're finishing drying and your session will begin. If it takes her a few minutes, don't fret; you're not on the clock until she arrives, even if the point has to be discussed later. Whether you wait nude or toweled, prone, seated or standing has been discussed at length w/o consensus. Take what comfort there is from all of us being a bit shy when naked, and focus on what a good time you're about to have, so you'll be smiling and happy when she arrives.
From here on everyone's session's their own. You're trying to set a mood and a menu that she'll work with so she's happy giving yo what you want. Just like any boy-girl relationship, except you're a paying customer, and the basic service is guaranteed (sorta) for the price: Eventually she'll bring up the services and the tariffs will be established. Often about halfway thru, after a straight massage. I prefer to save that time and establish 'my usual [Nude Reverse]' off the top. I'd tell her she was taking my cherry and that I wanted the NR I'd heard about, but that she was the expert and as a noob, I was trusting her. Worked for me.
You know the options—if you don't, read some more posts and/or search—just remember your good time will be in her hands, so the better time she has, the better yours is likely to be. Don't assume you can just poke, stroke and grab when and where you like. If she's confident you'll respect her limits you may be pleasantly surprised how few and how far they may be if she's enjoying herself. You don't want to find out how strict they are if she's not. These options are usually between you and her, discussed and arranged in the room, although that's not always the case everywhere. In Peel the bylaws allow upgrades to be offered openly, and they may be charged for at the front. In Toronto, all that's 'just between you and her'.
That happy ening will come w/o comment in any place where the girls dress sexy and the usual upgrades are offered. But NOT if all you pay is the doorfee. The girls' money comes from the upgrades. If you've picked a place where the MPAs wear ordinary street clothes or won'rt discuss Topless, Nude, Nude Reverse, or BodySlide, you didn't read enough reviews. You may stiil get a happy ending though; the usual lead in is, "Anywhere special you want massaged?" or from the client, some version of, "You missed a place/What about here". And you'll be expected to tip, wheras at the places w/ upgrades tipping is your gift.
Anything beyond a HJ, if it happens in a MP, is trouble for everyone except maybe the participants who manage to keep it secret. Do not ask. Do not tell. And while you're pondering it Google "prostitution Canada legality" or search TERB. You should knowe this stuff. You should also know that the more aboveground any MP is, the more it has fine-tuned exactly what can be done there and what will get it raided and shut down. For all their municipal licenses, no MP is more than tenuously legal. What you're counting on is that the good management that has kept them open, has been applied to pleasing customers like you. With nothing much else that they can take to the bank, you can pretty much count on a good time in any good place for your first time.
Then you can try to do better
