If you met a celebrity, what would you ask them?

Why do I always think of Game of Thrones when I hear this?

I (42F) have only been wearing what I’ll call “utility underwear”- the cotton, businesslike kind- for the last couple months. But the no -businesslike kind (lacy,silky) that have mostly been gathering dust in the underwear drawer have suddenly been showing up in my dirty laundry. My husband (47M) swears it’s not him touching them (he had a good laugh when I asked if he was wearing my silky panties to work secretly. He would tell me if he were). It has now been 4 times— including the last 3 consecutive weeks- that I have found a pair of black lace panties that I know I have not worn in my laundry hamper (which I keep in my closet.) I will say that they appear clean/unworn/un…soiled.
Other people in the house: my mom (70F), and my kids (13M & 11F).
I realize the 13M seems a likely suspect (eww). But he’s almost never home without me. And he’s about as sneaky as a newborn giraffe. My mom is home all day while I’m at work but … ???? Ewww. All scenarios I can imagine with other people give me the ick. Best case I can imagine is that I am sleepwalking, but given that I am tethered to a CPAP machine, I feel that’s unlikely.
What do I do? Set up a nanny cam to catch the perv?
Am I missing an obvious theory?
My husband isn’t totally convinced I’m not pranking him- or that there’s not some weird static electricity thing happening where they’re hitchhiking with other clothes- I think he’s just trying to avoid the family ick too.

Cuz technically, the next year one of you will be 18 and the other 17. Which is illegal no? One is a minor and one is an adult. I mean not that I think it's problematic or anything, it's just weird to me.

Also, does that mean that, if the 17-year-old wants to ruin the 18-year-old's life, they can just say that the 18-yo has been sleeping with a minor, which is illegal? I mean that would be totally ridiculous but it seems to me like that could be a problem for the 18-yo if their partner wants to hurt them.

I know nothing about what laws regulate this stuff.

?

What would it be and why?

i want them to look nice and clean for the Shelf

I had more to say but Reddit blocked it. He used to write genuinely engaging stories. Now everything feels like a segment from "Team America"
