Just move to LA...head to the corner of Hollywood and Vine...then just walk around that area with your dong hanging out...someone's bound to film you and...voila..you're now a pornstar.
This is exactly how Jack Nicholson became a star...btw.
i like shayd's idea also. pm one of the pornstars on this forum. They would know better than any of us. Try Belladonna or BrandiLove, i see their names alot
