Dad has recently gotten himself a much younger girlfriend whom he has moved in last month. My bedroom and their bedroom are wall to wall. The fact that they fuck doesn’t make me uncomfortable - so happy for them, but they do it on max volume. No joke. Every night at 11 and in the morning at 6 on the clock. These walls are paper thin apparently.
OP should definitely enforce boundaries, but this sounds like a fetish, which is fucked up, especially for the dad. If you’re an adult, you know your child is in the next room, and you’re banging at “max volume”, you’re wanting to be heard. 🤮
Doubtful.
I’ve been surprised at what and how much you can hear through a wall. Often it seems like you’re being silent, but that headboard is gently tapping on the wall and reverberating out the other side like a jackhammer.
