It's quite interesting that a site called Slut Load has content for gay users (because the word 'slut' is usually used to talk about sexually active women), but it does and well, it would be silly for me not to mention it here on My Gay Sites.
The archive is currently 200 pages long (and there are potentially more after that) when you look at the gay tag. I will note the fact that SlutLoad.com doesn't actually have a specific area for gay content, which means you're not going to be able to filter the scenes down any more than they already have been (unless you search, of course).
The quality of the clips here is probably the biggest issue and you'll also find that there are a few straight scenes as well. You can sort by rating, view count, duration and upload date though, so I guess that somewhat makes up for it.
