The only validation that's required of anyone is that which comes from within. That's hard to do, as any psychologist will tell you. (Read Alice Miller's Drama of the Gifted Child.) Porn isn't likely going to validate anyone who doesn't feel the slightest bit validated to begin with.
You're going to find people in every line of work seeking validation, or approval. It's all part of being human.
