I'm actually not all that big on lingere. I actually enjoy all of the cool printed panties that girls wear a lot more than lacy stuff.
And while I make an effort to notice and appreciate when my girl is doing something for me, I admit that things slip past me sometimes, and I'm sure I've disappointed her at times for not noticing something that she probably throught about for a good while. But she also knows that I don't ignore that stuff on purpose; it's just general male cluelessness about fashion and stuff.
As I said, lingere doesn't really do it for me that much. I like tight, smooth underwear far more than frilly, lacy stuff that's lumpy and full of seams.
Someone posted this link a while back, and I definitely enjoyed the printed ones (Hello Kitty/superhero/sexy saying/star wars/hearts/etc.) more than the lingere:
my boyfriend's not really into the whole full-lingerie thing, like the costumes? I'm not either, and we have a really similar idea about them - what's the point of putting on clothing when you're just going to take it off? yknow?
he also LOOOVES when I wear sexy/cute underwear! somedays I even chose my underwear for him..
