That's simple. The reason why most programmers are dealing with non-adult is because for some reason when you develop a system used for porn the development process goes like this:
developer makes prototype, company uses prototype as-is, developer gets laid off, company runs the said-prototype into the ground, company then realizes the difference between prototype, beta, etc and hires another programmer...and the cycle repeats
There is no money to be made in porn...if you're a developer (reputable/honorable that is...of course you can always find dirty work).

Anyways, I'm available for worthy projects.
