HClips.com is a porn tube that focuses heavily on amateur content. While the entire archive isn't of a gay nature, there is a gay category that has some 1,400 videos in that niche that are bound to put a big smile on your face (given that you are looking for amateur gay porn). The site has a number of features that allow you to sort content based on rating, popularity, length and upload date. What I will say is that there are quite a few threesome clips here and scenes of guys getting pegged by chicks. In terms of focus on gay material in the gay category, I'd say that this site has a pretty big issue.
The site doesn't have too much in the way of adverts and you are able to stream with some good quality Flash embeds. Scenes do have tags as well as descriptions which may make finding content a little easier. A lot of the material is uploaded by the people in the clips too, so that's something to note if you want a good quality community as well.
