LOL. I have matching lingerie and I also have some slutty underwear (trust me, they're not the same thing). The latter was bought for me by a guy who only got to see me wear it so his feelings wouldn't get hurt.
I love it when men think they know women oh so very well.
I love it when women think every other woman is exactly like them.
I don't think all women are like me. Not even most of my women friends are me or like each other. But when it comes to women's underwear, many men don't seem to know the difference between classy and brassy (nor, for that matter, sexy and slutty), but their wives and girlfriends tend to put up with it anyway.
I've talked to a lot of women who say they love sexy underwear. These are women who haven't been sexually interested in me, so it wasn't said in any way to impress me or for me to feel better about myself. My current girlfriend also loves sexy underwear. For most of the women who love sexy underwear, it is all about being attractive to their man. They love the way the man they love look at them when they're wearing something sexy.
