Hi Illucas :hammer:
I have experienced similar situation, although my lady residents do not use tampons and most are in depend pads, they too have desires and feelings, and I have witnessed some developing relationships with our male residents.
Most of the women are content to hold hands and occassionally kiss, but I have not witnessed anything else although some nurses have told stories that whilst doing rounds in the evening, they have discovered attempts of bed sharing. :-o
I have also seen many of the male residents who are quite demented gratifying themselves, usually nurses place a sheet over them but I prefer to wheel them into a secluded and more private area whilst they go about their personal business.
Some nursing homes have set up a room for communual rights of partners. we do not have this and I have not had relatives speak to me about this although i see the frustration of the husbands and wives when they come to visit. This is a need that does not get addressed within our everyday leisure and recreation activities although we should be seriously thinking about it. Also same sex relationships are there although one of the partners has become a resident does not switch off the desires of the partner. What can you do?? :-)
