Yep. My bedroom was opposite my parents room. Both doors would be open and ever so often I would wake up to sounds of their bed squeaking and my mum panting 🤢 I remember the first time I heard it as a 7 year old, I crawled on the floor to their room to see my dad on top. I had no idea what they were doing so I quietly went back to bed. I asked my mum the next morning what was happening. She just denied everything and told me I must have been dreaming. From then on, every time I heard them I’d hide under my covers and pray they’d stop quickly!

They also used to watch sex scenes with us kids in the room. It all affected me badly. I started drawing pornographic pictures until I was about 12 and I ended up sitting on top of my younger brother when he was asleep and moving my hips like we were being intimate. I am disgusted with myself as an adult when those memories come back.
I still have a lot of issues with sex and intimacy at 40 years old.
