What?? This is so nasty! A survey says that 45 percent of Americans said they have worn the same pair of undies for two days or longer. Thirteen percent said they had worn the same pair for a week or more.
Men were 2.5 times more likely to wear the same pair for seven days or more.
The survey was done by Tommy John underwear.
I'm going to say men are probably more likely to not change their underwear since some boxer styles are loose. With women our undies are in extreme contact so we have to change our undies everyday.
