In my time it was panties, but now I believe they've changed to boy shorts.
they never told us what underwear to wear when i was in school
We had a weekly inspection of nails, hair and underwear. Always a surprise, though.
We were required to wear those tights pants under our uniform. It's bad for the skin, crotch and makes you feel unbearably sweaty.
It's genitals, everyone has them. Babies, greatgrandpas, aunts, teachers, presidents,....
It sucks big time how disgusting pervey h*rny people ruin the lives for the rest of us.
