DBNaked.com is a database of well, naked things! While they have a more general segment for straight material, there is a category devoted to gay content that I think you're going to be more than interested in. Let's take a look and see what you actually get with this site.
Firstly, note that DB Naked looks at images. This means that if you want videos, go elsewhere! Additionally, the link I've provided you with will offer up a huge number of categories, ranging from amateurs through to bears and bondage. I don't know exactly how many there are here, but I'd estimate around 20,000 albums at an absolute minimum. The design is great too, so navigating through the content is a piece of cake.
Once you find a fetish, click on it and look for more material in that niche. There are professional scenes and a few amateur uploads too. The site has a pornstar database as well as a search function to make getting what you want that much easier. Overall, I'm happy to recommend this as a great destination to find gay images online.
