It's by far the most common
I'm not sure 'by far' is appropriate in this context. In the US, for instance, 91% of reported rape victims are female and 9% are male, with estimates usually of about 10% reporting for males and 40% reporting for females, which would yield an actual rate of about 28% of rape victims being male. That's hardly an inconsiderable number.
Though I'm not sure how many of those are in prison, however.
Where are you getting your numbers? They sound to me like they come from the National Crime Victimization Survey. These are not reports to police, but the result of asking random people if they have been raped. I don't think that they sample prisoners, so they are probably highly biased against prison rape, but should catch some.
ETA: There is now a third thread, so send new comments there.
Since the first thread has exceeded 500 comments, it seems time for a new one, with Eliezer's just-posted Chapter 33 & 34 to kick things off.
