Wife and I have had a pretty healthy sex life but our son who is in his 20’s has a new girlfriend and to put it bluntly they are always at it which isn’t the problem but the gf is extremely loud and vocal and we can hear everything,(they always stay here and never at her parents so we rarely get the house to ourselves) we’ve had a chat with our son but it hasn’t made a difference but now the girlfriend will even come downstairs in her skimpy underwear which I’ve said to my wife is slightly uncomfortable but now my wife has said she won’t have sex whilst they are in incase they can hear us. Has anyone else experienced similar and what was the solution?
