Ron Jeremy was on Tom Green's House Tonight a couple of days ago, he said something like this. It is near impossible for a guy to get a start in porn nowadays. They have plenty of guys already that they know can perform, so why should they take a chance on you? Even starting in gay porn is not a sure fire way to get noticed.
He claims the best way to get a break in porn is to find a girl that wants to become an actress, and enter the business with her as a package. Most people in the porn business want a new face, cause they hope she'll become the next Jenna. If she says "If you hire me, you hire him", then they'll hire you, cause they really want her and they will figure you two will already have chemistry. Then, when your with her, and you perform good,
You Might be getting offers for other projects. When you get big enough, you could go to Bangbros or something and maybe they'll hire you so you won't have to bang the same girl over and over for a career. But remember, you get paid shit. Unless your Peter North you probably won't be able to make a living out of it without working yourself sick.
And that's how you don't have to stick a pole in your butt.
