You love GIFs, right? Well I'm guessing seeing as you're searching the web for GIFs of gay guys, the answer to that question is 'yes'. Thankfully, I've got a nice solution to your problem: Reddit's very own /r/GayGIFs.
The rules are pretty simple: no underage content, all images must be GIFs (and animated as well), files are to be directly linked and people should avoid asking for sources. Pretty standard requirement for the porn community on Reddit and aside from that, there are very few limitations that make this place not worth subscribing to.
New content comes in around five times a day: it's a little slow, but given the niche nature of the material, it's quite understandable. The site currently has over 13,000 subscribers and between 20 to 30 people browse it at any one time. All in all, a nice, tidy subreddit that does the gay bros community justice. Check it out and have some fun!
