Good site for interruption-free porn, but... - I flipped out when I first discovered Redtube (on sitejabber, thank you very much!), and figured that this must be the free porn wave of the future. No more 5 second clips, popups, and links that just led to other sites. Excited by the clever name/logo combination that clearly uses the popularity of the ubiquitous youtube, I found youjizz. You'll like this site if you like fairly high quality, lengthy clips of free porn (who doesn't?).
BUT... the content is limited, as most of the contributions seem to come from Brazzers Network, 3rd Degree Movies, Peternorth.com, or Bangbros. Youtube this is not... don't be fooled, there most certainly aren't random people putting uploading their videos for us all to enjoy. This is a highly controlled site. Also, at least on my computer, the clips are very slow and choppy. I don't have this problem as much on Redtube. Content isn't added frequently enough for my fickle taste in clips, either.
One thing that it does have is a "plus" type membership where you can download unlimited clips and burn DVDs, which is good if you're into paying money and stuff... which I'm just not. Overall, I can't complain about this site, it's great, but isn't perfect. I prefer redtube.
