Is it normal to smell your underwear?
Mostly.Normal for most people
Yes, it’s normal to smell your own underwear out of curiosity or to check for body odor. Plenty of people do it, though it’s not everyone’s habit.
Underwear picks up sweat and normal body scents, so checking the smell is a pretty ordinary bit of curiosity or a quick hygiene check. Some people do it; others never think to. Either way, it doesn’t mean anything unusual about you.
If the odor is suddenly strong or unusual and comes with itching, pain, or unexpected discharge, that’s worth getting checked. Otherwise, sniff away—or don’t; there’s no underwear-scent rulebook.
