Don't get me wrong, I am not totally anti porn. Each to their own. I have been reading more and more articles about the impact of online porn on our children due to it being so easily accessible and frankly it scares me.
I have nieces who are 18 and 16 and they constantly post pictures of themselves on FB pulling "porn pouts" and basically posing provocatively. I also know that they have been active for a good few years. I know that when I was that age I was no angel (far from it) but I'd seen one porno (by accident at a friends boyfriends house) and was horrified by it. I certainly wouldn't have wanted to be viewed in that way. It seems like its now considered the norm.
I genuinely hope that restricting access makes it less "normal". Its a bit like an online version of having to go to the newsagents to buy it. It doesn't ban it, it just makes it something you deliberately have to access.
