The thing that turns me off most is a bad attitude. As soon as you step inside their room, try to determine what the provider is like. If she gives off negative comments and a bad attitude, then leave immediately. Do not attempt to work things out and see if they progress.
A good provider will greet you with a hug, a kiss, or some form of pleasantries when you arrive. She'll get to talk to you for a little bit to get to know you, or, she's already butt naked and ready.
She doesn't demand the money right away, and she doesn't direct you on how to perform. I'll give you an example. She immediate ask for donation as though that is the only thing on her mind, she instructs you, yup, instructs you to lay down with no form of foreplay, can't suck on tities cause they too sensitive, can't touch pussy, can't touch body cause your hands are too cold, can't do this, can't do that. Well, WTF is a client suppose to do then?
Some of these girls got a routine goin, and take advantage of suckers. If you leave right away, she'll learn. Even though you've wasted time, you'll save yourself a headache, money, and a disastrous session. If only all men are like this, these providers wouldn't exist. However, because some hobbyist do take their bait, they continue to exist, and pull the same shenanigans.
One method to avoid this is checking for their reviews. See if they have good reviews or not. The second method is to determine their behavior as soon as you enter their room. Try to have a conversation with her, and if she is friendly and provide good feedback, then stay. If she's not friendly, doesn't take directions well, and gives off a bad attitude. Then leave immediately. Don't try to work things out and expecting it will get better.
