If I had a pound for every time I've said that to myself...
But seriously, to echo the sentiments already expressed by a certain poster: it's nature, so why fight it? I periodically download and bookmark a few amateur porn videos and image galleries etc, only to delete them all in a sudden boycott, then redownload them all a few days later.
I can't wait 'professional' porn anymore, as it's completely passionless, there are less variety in terms of actresses and actors, and it's just 'not good', really. Most of all though, for me personally, it's because professional porn isn't 'real'. It'd never happen like that, and even if it did, the grotesquely stupid and overacted way in which it is performed is a sure boner killer for me. Amateur porn any day of the week. Real passion, real romance and real fucking from the average Joe and Jane.
I'd also like to say that porn hasn't necessarily killed my libido. Being only twenty-one, I essentially grew up with the internet (having the first available broadband in the UK in 2000 or so), and have been watching some kind of porn ever since. So, about eleven years old, really. It hasn't affected my relationships. Though, it has awakened me to may fetishes, acts and positions that I probably wouldn't have discovered if I were born say, in another era.
I don't have any absurd expectations in my partners (having model bodies or pornstar breasts for example), which in my opinion, makes it all the hotter once you actually see such a lady on the street with those assets.
It's just porn man, and I haven't let it skew/distort my realistic view on women.
