People have been masturbating since... who knows?

Where does it say they are not allowed to masterbate? Perhaps not masterbate and sling the stuff on the female guards, perhaps not do it right in front of other people. I don't remember it being allowed on the outside of prison either, do you? Lets keep the discussion real for the time being.

Privacy booths in the cells? The female guards don't need to ogle some guy cleaning his pipes.

"...sling the stuff on the female guards...Huh? Is this a diathalone shot-put contest. Personally, I seem to remeber as a young man, using a sling-shot with a steel bee-bee aimed at a paper target. I think that some Jewish kid used a "sling" against goliath. Somehow I don't get your point in terms of "slinging... stuff" at guards. Can you clarify this, your statement in terms of "slinging stuff?" Sounds like a pillow fight to me.
