[NSFW!] What reason do you have that would make adult entertainment a “no-no” for you to do?

Off many of the answers to this question, it made me wonder what would be the big aversion to having sex in front of an audience or camera. Would it be basic shyness? Having it be immortalized on film or digitally many years in the future? Being “out there” where you can’t control it? If you say ”I can’t do that”, why not? What if you were, offered $50,000, somehow, could you then? What about if you were offered $200,000 still no go? Would you still turn down boinking in front of the lens for 1.4 million or more? If you think ”I would do it for 1.4 million” what changed? What makes it easier to do at 1.4 mil than for $3,000?
