You just need to be smart with how you play the game when you enter these places.
Unless you get completely naked, you should never expect anything more than just a massage.
And unless the place is brand new, always say that you have been there before when they ask (and they usually will). If they ask for a name just make one up and play it that way or just say you can't remember because it was a while back (these places usually have plenty of turnover so you'll probably be safe). Don't be afraid to touch the provider a little when
the massage starts as well - a little touching and feeling goes a long way to making her feel more comfortable with you. Being cool and calm is key, these ladies can sense when someone is nervous or stressed and then it's game over.
