Is a choice now a choice for always?

So I am jobless again. Well, that's not entirely true. I have a job teaching chess to elementary school kids 6 hours a week. But that is hardly something to live off of. I have the same questions running through my head that I have for years. Why haven't I tried the adult industry?
I'm not shy. I understand the difference between consent and violation. I'm good at defining and communicating my boundaries. I'm very creative and would probably be a lot of fun to work with, and I bet I'd have fun on the job. And I need money. Now. So why don't I take the leap?
There is the puritanical, societal fear in me that if I 'go there,' there's no turning back. But there are millions of adult website and adult video production companies. That a parent or fellow teacher would recognize me is highly unlikely, about the same probability of getting struck by lightning.
And why isn't it something I couldn't do just now and then? It's not like every job you take is a career choice. Am I afraid that I will like it? Or that suddenly, I will have a scarlet P (for pornographer) embedded in my face, and people will know. Or is it that I would have to be dishonest with my mother, tell her I was doing individual performance therapy or strange experimental videos. Really, I don't see how it could affect me in a negative way.
But there is till this question, 'What if?' Like jumping off a cliff.
Would being a pornographer actually give me the financial freedom to do the kind of projects I wanted to do? Could I make educational videos about sex? Sure I could. It's just getting the puritans in my head (and there really aren't that many) to shut up. I wonder if I'll take the leap.
