I've thought about doing it, it sounds like you can make some money with it. I don't think I would, though. I've only cammed with my guy, and I enjoy keeping it just between us, like a part of me that only he gets to have.
I think it's a perfectly honorable thing to pursue. Just be safe. If I were to do it, I'd first research the privacy of it. Is it likely that future and/or current employers will see you? Is it common to just not have your face on camera?
