I'd have to say cock wise.... yes. However like some others have mentioned its about more than just your cock. One way I've heard it put before is if you were walking down the street and a woman stopped you on the sidewalk and told you to pull your dick out right then and there and that you had two minutes to get hard would you be able to.

new pics uploaded, sure its gettin bigger hahahaha

Yes. But size is not all that important for porn. Sure, there are a lot of porn performers with monster cocks, but there are also performers with regular size and even small cocks.

It comes down to temperament. Could you report to work, punch the clock, take off your clothes, have your ass make-up applied and then have sex with someone you don't know and might not even like while others were watching and the cameras were rolling? And could you make that sex look convincing, as though it were the best fuck you ever had?
