You flap around as a male. You also risk catching yourself in your fly. You will also need to wash your pants a lot more quickly. This is a consideration if you are talking about dress pants or pants for work.
If male: you dont. If female: dont wear underwear
underwear
Some do some dont some dont wear any underwear
No. Men and women wear underwear to bed all the time and nothing bad happens to them.
No, its fairly unhygenic. I dont suggest it.
You will pee/poop in your underwear
It is optional. Some wear and some dont.
Why? Dont wear pants at all.
Some men don't wear underwear because they feel it is restricting. There is also concern that the friction and additional heat can reduce sperm count.
you should put in a tampon and wear a pad in your underwear
you dont really have a cool type of under wear but personally I dont wear boxers I wear breifs or boxer breifs because it holds it all in... if you know what i mean
underwear, socks, tie, shirts, pants
