Go to the web site of a porn producer who makes the kind of porn where you would fit in. Look for a link that says "Want to Model" or something similar, click on it and you're off and running.

It's a common misconception of the puritanical that those who do porn have hit bottom, are desperate and are being exploited. I'm not saying that exploitation never occurs in porn (it happens in every industry). But the truth is that the vast majority of women who do porn and virtually all men are doing it BECAUSE THEY WANT TO DO IT. They find it fulfilling and satisfying to put their bodies and their sex on public display.

If doing porn is something you want, go for it. You'll be glad you did.
