I'm very sorry Chelle but I have to agree with your wife. Although "panties" has historically been used as a term to refer to women's underwear, underwear is underwear. The term panties is actually falling out of use. And I'll have to say that I am shying away from the term myself as almost becoming a patronizing or patriarchal way to refer to woman's underwear. Similar to how "gurl" was once accepted to refer to girls like us, but no longer is generally accepted, I believe "panties" is heading that way also. But that is just my opinion.
