Porn OXO is an adult tube site that offers its users the ability to enjoy various types of entertainment of an erotic nature. Yeah, it's your run of the mill tube that has a gay section and I figured I'd mention it because the readers of My Gay Sites just love a bit of variety when it comes to adult tubes.
So anyway, PornOXO.com doesn't actually have a completely separate area for gay scenes, which means that it's not possible for you to filter the content past 'gay' unless you use the search. A little bit inconvenient to be honest, but hopefully they change that soon.
Filtering material is available by sorting the gay videos by rating, date added, popularity, number of comments and length of the video. I wouldn't say that it's the hottest tube on the Internet today, but it certainly doesn't do a bad job of providing you with good quality gay content.
