I've looked at those sites, and like I said there's no scientific studies that support this being true. Peoples supposed testimony on an unreliable commercial website doesn't make this thing real. Just because people look at porn and have ED doesn't mean that the two things are related. That's purely anecdotal. There needs to be cold hard peer reviewed studies to support this. So far there's only been a few recent studies and they've found no relation between porn and ED but there needs to be more studies to be really conclusive. Commercial websites are not a reliable source of information.
