From what I hear and see in the media, that's kind of what happens in prisons where you put a bunch of men together with no access to women. Lately, some female prison workers have been in the news for getting it on with male prisoners. Guy's in prison probably aren't all that fussy about how or who they get off with....ugly men, ugly women, the mattress or a pillow, etc.
It's nothing like it was 20-30 years ago but it does still goes on. I'm talking about rape though. There's still plenty of rampant consensual homosexual sex behind bars. That's only a prison thing though, that shit ain't going down at your local county jail.
I think it's fascinating to see how men handle being put into that situation. Locked up sometimes for 50+ years with no female touch or love. Prison is such an interesting aspect of the human race, specifically American prisons.
