As a Director probably...
But more than a Porn Movie I would gladly do a Strongly Story-based Movie with some explicit Sex scenes.
About Performing in a Porn Scene... Well, i Would gladly try but I heard it's a HARSH buisness... even more than many people imagine.
So probably I'm simply not up to the task, and I don't have the motivation to work hard to enter in a world which, besides it has it's charm, it's not fit for me.
Again, I'm probably more fit for some work as a Plain Actor who Occasionally has to play a Spicy Scene.
