1, recommended for pajamas. Many men are used to wearing a pair of underwear at most when sleeping. In fact, this is not good for their skin health. Because you don't wear pajamas to sleep, the oil and sweat secreted by your skin will remain on the sheets, and the sheets are relatively large, which is different from the clothes you wear in peacetime. If left for a long time, it will breed a large number of bacteria and cause mites. If they sleep in pajamas, they will clean them in time to avoid the above hazards. Therefore, it is best to be male.

This is a personal habit, regardless of gender. From the perspective of scientific health preservation, sleeping naked is good for your health, but it is inconvenient if you are at school. Whether you are a boy or a girl, if you like to sleep naked, that's normal behavior. Don't worry about anything, it has nothing to do with gender. It depends on where you sleep.
