Interested in the power dynamic

I've always been interested in power dynamic and love the idea of someone letting me play around with their brain and feelings and emotions. The financial control is a nice touch from a financial perspective. But from what I'm seeing so far, to find a sub, you have to be willing to show off your body to the whole damn Internet.

I would much rather have someone work for the privilege of seeing my body and prove their worth to me. Isn't it more fun in an online dynamic to have total control of your image?
