Oh dear Marie. I’ve a similar house to yours, yes, it is so embarrassing. If you have a next door but one neighbour presumably they’ll hear it too. In my case when I mentioned the ‘man sex’ [the guy next door and his boyf sounded like grunting bears!] to my NDB1 neighbours, they seemed relieved that they weren't the only ones hearing it and said they’d bang on the wall and presumably did because it went much quieter. Also my neighbours who used to live at the other side were having a regular Sunday afternoon session with the bedroom window wide open when my daughter visited. We sat in the garden, the familiar sounds started,
daughter turned to me and in her usual loud, clear voice, said, ‘What’s that noise?’ It stopped instantly. Then she exclaimed in same usual loud, clear voice, ‘Well THAT didn’t last very long!’ Problem solved! It still makes me giggle.
