Is it normal to share underwear with your siblings?
Depends.It depends
Some siblings share underwear, but most people prefer to keep it personal. If it’s clean and freshly washed, it’s generally not a big deal; worn underwear is best kept to its owner.
It happens in some families—usually because laundry got mixed up, someone borrowed a pair in a pinch, or people just don’t mind. But underwear is a pretty personal item, so plenty of siblings would find sharing it uncomfortable, even when it’s clean.
The practical rule is simple: share only if everyone’s genuinely okay with it, and make sure it’s been freshly washed. Don’t pass around underwear that’s been worn; it can spread germs or skin infections, and nobody needs that family heirloom situation.
