As if that's bad enough, even the correspondence you have with your spouse/gf on the outside has to be carefully worded, lest it be too titillating.

Photos too-- if it's too risque or pornographic, it's subject to confiscation.

Considering the lack of conjugal visits, it makes it just that much more difficult to maintain relationships with anyone on the outside.

(Of course, every prison is different, but this was the case in Escondido as recently as a decade ago...)
