discussion on boys in girls panties

i know sum1 hu's like this..he's a relative actually,,he wear panties instead of briefs, but he's straight guy, i ask some of our relatives why he's like that, i find it wierd actually but later on i understand, i've learned that he's having some allergy in wearing briefs and he's not comfortable in briefs...but he wear boxers..we dont have to judge people by what their wearing ..
