If you love asses of men, then boy - have I got a treat for you! Yeah, it's another subreddit filled with pervs that love guys and it's called /r/ManAss. A great name, a great product and after taking a look around, some nice material too!
Note that while Man Ass isn't 100% devoted to gay material, I can say with confidence that this is pretty much exactly what you get. dudes in jockstraps, twinks taking mirror selfies and gay pornstars showing off. I mean, it doesn't get much more homoerotic than that, does it?
Anyway, /r/ManAss has close to 6,000 subscribers and has been a community for over 4 years. I don't know if this helps sell it, but /r/ManAss was actually created by a user called PenisLover. Anyway yeah - check this place out if you're down for some hot booty of tasty gay studs.
