Spank Wire is a pretty popular tube site and I think it would be a little silly not to include this on the list. You'll find that in order to access the gay content, navigating on over to the gay tag is the way forward. I've linked it as the outbound location, so you don't need to worry too much about finding it.
Anyway, the gay section has a huge number of videos to enjoy as well as various sections that make sure you get the cream of the crop. We're talking top videos, featured clips and those that have been uploaded in the last week. Note that Spank Wire is not 100% devoted to gay content, although I didn't see a single straight scene in the entire collection here at Spank Wire.
Incidentally, Spank Wire is also owned and operated by the same guys that run Porn Hub, Red Tube and You Porn. Lots of x-rated material on this network and if you really want the top site they have to offer, check out GayTube.com.
