/r/MaleUnderwear is a subreddit boasting just over 6,500 subscribers that are interested in the sharing and viewing of pictures and videos that deal with guys in underwear. Now I know what you're thinking: is this where dudes share details about the best pants to wear when hiking? Hell no: it's all about guys in different forms of pants!
While the material is fully primed for enjoyment by fans of men, you have to realize that not all of the submissions feature dudes that are gay. The types of underwear vary too: you're going to see thongs, boxers and plenty of things in between. There are no rules here except to link to content directly, have the content be high quality and of course, relevant to dudes, bulges and underwear!
Fresh updates are populating the subreddit around five times a day. It's quite good to be fair, because this is quite clearly a special interest subreddit!
