My Gay Sites is obviously all about gay sites, and while I try to keep things as gay-happy as possible, I do think it's important to help people find sources of content that might interest them but not be directly related to the theme of the site.
Okay, I'll stop talking nonsense now and get to what I'm talking about: /r/Chastity is a community on Reddit with 7,000 subscribers that like to see people denied sex and locked up for good. Now I should make it clear that this particular chastity destination does have some female submission material, and the lack of tagged content means you can't filter it out easily. Still, I'd say that around 80% of the content is of dicks, and of course, I should warn you again that not all of them are of guys that want to submit to other guys.
So yeah, in short, this is a good place for you BDSM freaks that want to see little cuck cocks locked up and denied pleasure. New submissions are made around 10 times a day, so it's quite popular and has a fresh stream of gay chastity for you to find every 24 hours.
