xHamster is surely one of the biggest porn tubes out there and I think it would be mighty negligent of me to put together a list of the best gay porn tubes on the Internet without including it. Naturally, xHamster isn't a site that is 100% devoted to gay porn, but if you search 'gay' while on the site, you'll get taken to an area that has nothing but the best in cock and bum fun.
The site has thousands, if not millions of gay clips for you to check out. There's a special feature here that some other tubes don't have and that's the ability to filter out any scenes that are not high definition. Of course, you can also sort clips by their ratings, so if you want to see what people enjoy most here on xHamster, it's really easy to do that.
The site has a nice design and the thumbnail display of material is clean and minimalist. All in all, this is just a great tube you should consider checking out.
