The horndog who lives in my brain shouted, "hey, hold it, you just passed some gay porn." So I scrolled back and found this.
Taken in 1937, the photo shows four college football players having a shower. The two on the left are halfbacks, the one center right is a fullback, and the one on the right is the quarterback. It wasn't meant to look like porn then, but it looks like that now.
Now I don't know anything about American football, but I have taken a shower or two in a locker room in my day. I don't ever recall blokes standing this close together, soaping up and rinsing off, unless it was in some kind of porn scene. Real men give each other more personal space than this.
I imagine they were bunched together so they would all fit in the photo. In 1937, that wouldn't raise any eyebrows and most anyone seeing this in a newspaper or magazine would think nothing of it.
But I'll bet some lads cut it out to save. Their minds went deeper, much like the horndog trapped in my brain. This would be pure fantasy-generating material in an era when gay porn was non-existent. The lads on the left look like they're actually touching groin-to-groin as if they've got some frottage going on.
And one other thing -- the quarterback on the right who looks like he's buttfucking the fullback? No joke -- his name was Elmer Logg.
