Is it common for mens' cocks to get bitten off in prison? I mean, if someone tried to rape me and stuck their cock in my mouth I'd bite it off. Does this happen much?

No, because while that man is bleeding out he's ganna fucking end you for biting his dick off. If you manage to survive by some miracle his gang buddies will beat you senseless, rape you, then kill you. So you suck that dick like a good prison wife, and shut the fuck up.

Only someone who doesn't hang around /lounge/ will chomp the fucker off and grind it down.

It happens, but not often. If he bites, then they just bash the guy's teeth out so next time he can't.

Basically would you rather suck a dude's dick, or have all your teeth knocked out and then end up being forced to suck dick anyway.

But it must still happen sometimes.
