We all have different tastes. For example as a CDer I don't understand the obsession of other CDers for panties and bras. I like them, but not to the point of underdressing, sleeping in them, or buying a collection. I don't like lacy, and downright hate frilly stuff. On the other hand I am a total fan of pantyhose.
My wife buys lingerie, she hates frilly stuff as much as I do, but likes a bit of lace while I'm not a fan of it, so she's definitely also buying for her, not just for pleasing me, which I think is a good balance.
