Wiggles makes some excellent points in his post on how to make the most of your AMP experience. I'd like to add a couple of things as well. I've been to massage parlors all over the world, AMPs and incalls / outcalls I find on backpage or the local weekly entertainment newspaper. I prefer massage "therapists" to escorts because the session is all about me, and usually much cheaper than a good escort.
I agree that the providers first concern is that first you are LEO, second a threat to her. I don't display my work badge or anything pertaining to my company for my personal privacy or use my real name in most cases either. But I always call ahead and make polite conversation, ask if they have a table shower (a real plus in my book) the price for an hour, and what is the address. Then I go. Once in the room; GET NAKED. If you leave on a stitch it raises a red flag. In some states a LEO getting naked spells entrapment, not sure about Michigan. When she comes in, stand and face her, smile and say Hi, introduce yourself (if a different woman than let you in the door) , again displaying yourself will lower the LEO fear. Don't worry if you have a little unit, they don't care, they only want your money.
Then lay down and just relax and enjoy the massage. You'll know if it's going to be a good ending if she teases your backside and beans and frank while doing your thighs. It's perfectly acceptable to spread your legs a bit, and raise up to give her some access while she's teasing. Now she's pretty sure you aren't LEO, and you both know how things are going to go. Relax totally, succumb to the pleasures of the massage. If the only reason you are going to a MP is to get off, you are missing most of the hedonism. When U-turn over then things vary. Some girls will ask what you want, some will point, some will just do what they want and wait for a tip. By doing your homework on this or other forums you will have a good idea what she expects for her efforts, so have that amount available. Wiggles mentions 120 to 140 extra. I've never paid that much in my life. Of course I only want an HE usually, some times a BJ. FS after a good massage is just too much work. I never take in my wallet, just the amount of cash I'm willing to spend. Oh, always cash. Don't be stupid and use a credit card. Once they have your number who knows what you will end up buying for her, or the AMP owner.
Some experiences will be excellent, some not. Just like most of the women we've known in our lives, not all of them were tens, but all were worth knowing if only for the education. Go in with the expectation of relaxing, and being the center of attention and you'll get a lot out of it. As I said, it's all about you.
