A woman may not want to show her body. It does not make sense to pay a webcam chat session where the webcam model does not want to show her body in a world where women show themselves everywhere on social media.
Here is my technique in this situation. In a public or group show (with reasonable fee), I wait 5 minutes. If after 5 minutes, the cam model doesn’t show anything, it is time to leave and remove her from your favorites. These women are a waste of time. They just tease their audience by taking advantage of their attractive beauty (if you can see something).
To my observation, no deceptive cam models changed their behavior. There are enough fishes in the ocean. Don’t waste your time with “shy” women who came online just to get men’s money without giving anything in exchange.
Don’t spend your time chit chatting with such woman. This will not improve the situation. If they decided to be webcam models, they decided to become public figures. They must show their body online.
Better focus on webcam models who show their body from head to toe.
I once saw a ridiculous situation where a webcam model uploaded a dozen bikini photos to her webcam profile, yet refused to stand up in front of the webcam and show her full body to the webcam on a live stream.
