I'd guess that other people watch porn exactly as long as they get "excited" enough to do something I don't describe here. After this is "done", there is no need to watch more of it for at least the length of the refractory period, but better for longer.

Why would one continue to watch it afterwards? One can't be addicted to porn under my definition, but just to doing "that". This can of course be addictive and negatively affect one's life. Also the stimulus surely can get weaker and weaker thus leading to "harder" porn each time which looks like a bad cycle
