8-) Well I have experienced the same thing in our home. We now have a man that comes to see his wife that is totally confused, but has a girlfriend on the other unit that he comes and make out  with in her room. At one point he was still having sex with his wife that was and is totally confused. Which I felt was wrong when I first started, but as a husband he had the right and we could not stop him. We also have had two residents that wanted to room together but their kids said no! The only reason the kids had a say in the situatuin was because their father was becoming very confused and wasn't as oriented as the female anymore. I agree that the staff acts so holy when it comes to the residents doing what makes them happy. Everybody felt it was wrong for the gentleman to have a wife and a girlfriend. That at one point lived across the hall from each other, till he had a feeling his wife knew what he was doing. So he moved her. I feel, just because they are in a facility that we have the right to dictate everything. So let them enjoy it while it last. They say the best way to go is HAPPY. Please let the families know and I agree document the sex, because it is a physical and mental activity.
