The best strategy I have – and this doesn’t ALWAYS work – is never to give them EVERYTHING they want. When you’re in free chat with a potential client, tease them with talk but refuse to show any nudity until they take it private. Then, when they start asking you for this, that, and the other, you do some of it, but not all of it. Once the show is over, invite them back “soon” for “more”.
The strategy is to just be yourself. If there is something about you that they like, they will be back. Or maybe you can come up with a “signature” move. You might have to try a few until one that you are most comfortable with.
