In one particularly sexually active period of my life, among others I was sleeping with a couple particularly loud women, to the point that my neighbor complained to the housing office which we rented from.
The housing manager knew me, my flatmate and I had many parties there and we have had many conversations and letters from him. But he was generally light hearted about it, just doing his job. He called me and said “so your neighbors complained about the noise coming from your apartment from certain… recreational activities.”
I offered to get some music studio purposed sound proofing foam, and we joked about it and discussed it. I ended up getting a bunch and attached it to my walls, and indeed I heard no complaints thereafter.
