NSFW (because I am careful)- Is it more of a character flaw to be an adult worker or to pay another for adult work?

Neither are flaws.

I agree with @judochop
Also what both of them do is really none of my business.

I’m not sure if I would call it a flaw but I see in terms of the worker having a need and the customer having a choice. I’m not a fan of sex work and would be less excited about a person I know being a customer than someone who refrains, for so many reasons.

If I walked into a strip joint and saw someone I knew working there, I think it would be kind of cool. Something in common. I mean, in all the rest of my life I have never known a performer whose medium was erotic arousal. They all seem like strangers and I have no idea why they do what they do.

Neither, one is buying a service, the other is providing a service.

Gotta go with neither on this one; I can see where there could be perceived flaws but they’re of the individuals own making beyond the scope of the questions conditions.
(ex. if you are lying about what you do for a living or your patronizing of such enterprises because you believe what you are doing is morally wrong or condemn others for the same activities.)

I’m in the “neither” camp, too.

Sort of related: When I was younger, I used to wonder how I’d feel if someone was watching me in a bathroom (like a hidden camera or something). It would make me feel paranoid when the thought would pop into my head, until I realized that if anyone ever was watching, they’d be far more embarrassed to be caught peeping than I would to be caught peeing. In other words, if the other person’s embarrassment is equal or greater, there is nothing to be embarrassed about.
