Sorry to disappoint you joe, but I've worked in only all-male correctional facilities over the past 23 years. Besides, you forget about the female teachers, nurses, doctors, secretaries, food service workers, counselors, probation officers, etc., that work in prisons and have to interact with inmates.
New York State allows porn magazines. I'm a supervisor, and when I see the guys bring their magazines out to the yard, etc., I bust their chops: "Ah, heavy reading tonight eh?" Most of them say: "Oh, these aren't for me...I've brought them out for one of my friends." Yeah, right! I especially like to break 'em on the Muslim inmates who bring the mags out to the yard. Their religion prohibits them from even gazing on a female naked if she isn't his wife. So I say to them: "You know, Mohammed/Allah wouldn't like that!"
Inmates are going to masturbate whether they have magazines to look at or not. While I have no use for porn myself, I think California has gone a bit overboard. All these so-called females have to do is report the masturbation if it occurs in their presence. There are afterall, rules governing that type of stuff within the prison system. I could care less if they do it in the privacy of their cell, cube, etc., just so long as I don't have to view it. And on that subject, I can't remember the last time I had an inmate flash me. It's been at least 20 years I bet. Perhaps it's because I'm an old lady, and a supervisor to boot. They do it just to see how you're going to react anyway, and there are several different ways to deal with it. It's never been a big problem in any of the facilities I've worked in.
