It probably doesn't add anything, unless you're a man that likes to watch your wife fuck another guy. Kind of like watching your fantasy played out on screen. But for the guy actually on the set jacking off to a live porn show, hell, that would be a blast!!! I doubt very seriously that the men care if the guys at home watch them jacking off, or even what the guys at home think about them jacking off in such a scene.
