I have only had my stuff found. First time was when I was about 14 and my grandfather was putting my clothes away and opende the drawer were I keept them. I said to my parents that I dont use my dresser and dont know how they got there. Luckily I had a older brother that I knew was gay and played it off on him. They took the bait.I also shared the room with him.
Second time was by my wife. she found a stash I had of her old stuff.
I shared with my wife once that I did this. She was ok at frist but then a day or two later she was unhappy about it.
Not to happy with that move was she.
