The concept of “virtual sugar babies”

I don’t understand the concept of virtual sugar babies. I am not sure if I am the only one who thinks this way. What’s the point of having a virtual one ? May be people don’t understand who sugar babies are ? If I am going to have someone who is going to blast their nudes to multiple people and calling themselves as sugar babies is something I don’t understand. I might as well watch some good porn and satisfy myself. And the amount they charge is outrageous for it. It’s as much as my three years Internet bill for a month ? Seriously?
