We had a similar kind of discussion last week. I think it does fuck you up,Seeing constant fanny and tits on video and in pictures numbs the mind so when you finally see real ones it's hard for your brain and penis to react. I was having a situation where I was losing an erection actually watching the porn as it no longer gave me a kick.
So recently I've had a complete porn detox, no porn at all for the last few weeks as I was on holiday with no laptop and finding actual real women's company a lot more interesting and sexy.
It's certainly reset my libido, I was waking up with some absolute massive and hard erections, a change from the soft half semis I was having. If you're a guy looking at a lot of porn daily,see if you can give it up. Just for a month at first, as a test of wills and you'll definitely see an improvement.
