I don't know what the obsession with foreskin is, but some gay bros out there are just obsessed with that useless piece of skin that covers a dick. I'm personally cut (not Jewish, so I have no idea why!), so I might have a little hatred for this place in my heart, but it seems that as long as they're not shaming bros for being a little low on skin material around the cock, it's not that much of a problem.
/r/Foreskin isn't devoted to gay material, but obviously, there's a hell of a lot of dick action here for you to enjoy. The subreddit currently has over 8,000 readers and fresh submissions are actually pretty frequent with around ten new submissions coming in on a daily basis.
Take a look and if it tickles your fancy (or your foreskin), subscribe and enjoy. There are dicks abound here at /r/Foreskin.
