What?
I am confused by your statement. Are you saying porn causes ED? I would casually think that would mean most men would have ED :)
A quick search of the web [1][2][3] shows several Psychology and also Medical papers showing porn does not cause ED. Wondering (if I am reading your statement correctly) where you correlate porn use to ED. I think that would be newsworthy.
