What I do is a bit of
naughty4u1976's advice with my own spin. I like to keep it simple.
1. Take no more money than youre prepared to lose (house + donation. do research beforehand so you know how much leeway you have)
2.The wallet and anything you cant afford to lose stays in the car.
3.If its my first time at a place I let the girl see of all the money in the room and I say its "for everything" so they already know. 9/10 this also kills having to negotiate or deal with upselling unless the girl upsells for "religious purposes".
4.I rub up and down the girl's leg throughout the massage to gage their reactions and see if fun is on the table. If the legs open wider and they give you the sweet spot, stop worrying. If they let you go beween the legs and up to the rear and you dont feel any underwear. Sit back and enjoy. If neither of those happen, sign language might be needed on the flip. If they dont want you touching them, they will tell you. Ocassionally Ive had fun girls be resistant to touching because they want to focus on the massage but theyre outliers.
Im WAYYYY older than you but I do nothing but work out since retirement and women always tell me I look like Im in my mid-twenties. So the response I get nearly every time I go to an amp is "fit = LEO. We scared". I ended up making my routine before I even knew review boards were a thing.
Usually I dont even need the sign language once the flip has happened. I nearly always know if Im getting what I came for before it reaches that point. Ive only had one lady still be nervous and that ended after I pulled her into dfk. I dont recommend that in hindsight.
