It's a bit off topic but I read somewhere about people giving up porn because they felt it impaired their sex functions and people said not watching porn for whatever amount of weeks made them feel like totally new people, appreciate life more and all that. I mean I guess since it's a psychological problem to begin with placebo is going to be a good cure, but not watching porn seems like a bad cure. Especially with all the stuff out there, like the site the TS mentioned. :) I mean I guess that's a condition for people who literally can't have sex because they've watched too much porn, but still sounds like extreme cases to me.
Anyway, I am a bit worried about this stuff, if it's one thing politicians can get behind it's hating on porn for some reason, I fear there might be something like this here in Sweden too some day.
