Conjugal visits often come under fire as a way of corrupting or traumatizing the kids of the person in prison.
In reality I think it is much better for the kids to understand that their parent did something wrong and is in the grown up equivalent of "time out". That way they know for sure that it is nothing that they did to drive the parent away. I've known kids who didn't get to see their parent while he or she was in prison and invariably the younger ones think they somehow did something to drive the parent away.
People are focusing on conjugal and familial visitations as effective rehabilitative concepts, when they should be focusing on the kids and what they get out of it.
