My wife prefers to buy no lingerie. Big sleep shirts and flannel jammies (depending on the season) are the rule of the day here. I understand it. Her body, her clothes, her preferences. Just because I'm accustomed to it, though, it doesn't mean I wouldn't appreciate a little effort on that front from time to time. As I say, just disappointing.
Have you ever made comments to her about it? I think sometimes we forget that we need to still try to look sexy for our man.
