I have had several friends that worked as prison guards,and my understanding is there are women guards in male prisons,and male guards in women's prisons. Nobody says anything about it,but I am guessing the male guards are VERY reluctant to grab a female inmate,though. The lawsuits would be never-ending.
Men are generally not programmed to respond to a vicious, aggressive, no holds barred female.
It isn't there, it's awkward, and not responding appropriately can lead to serious injury. Responding appropriately can lead to a lawsuit. Same with propositions, damned if you do, and accused if you don't.
It's a no-win deal for a straight guy.
