I find this quite a strange one.... You will often find on general swinging forums a note that says 'we NEVER allow anyone to stay over'.
Perhaps it's just my background... but if I welcomed someone or a few people into my home for the evening, and where it was likely that guests may have a drink or two, I would find it rude not to offer the option for them to stay over - esp if they had travelled a distance. Whether is was for a general social, a game of bridge or something more intimate
I would find it merely courteous.
Am I alone in this???:hmm:
