You would have to have the man know beforehand about the video. And most likely he will want a percentage of the video per show. Some of your clients might be kinky enough to not care about percentage, and just like the idea of himself fucking you on worldwide web, but most likely, clients do not want to be seen publicly, as they have families, wives, coworkers, relatives....
You might want to contact some of the male escorts and see if they are interested. They will just ask for a percentage.
