I only allow my picture to be taken for ID cards, or for polaroids, with a featured exotic dancer, where I get the only copy. Sometimes an Escort likes to take 'porn photos' with me, on her phone, but they're deleted before the session ends. We just look at them, between shots and SOGs. They then exist only in our memories, like a live performance of any kind, that is unrecorded by audio or video capture. The Escort can keep a 'dick pic', if she asks nicely.
There are no digital photographs of me on the Internet, to my knowledge. Why anyone would want to voluntarily give that sort of information to social media sites is beyond my comprehension. Perhaps those people don't travel internationally.
I have a mirror, if I want to know what I look like. A photograph of oneself is necessarily is in the past tense. In addition, my eyes tend to look red instead of blue, if excessive lighting is used. Me no likey.
