I had these same fantasies, and still feel them occasionally. I'd be surprised if quite a few of us didn't, at some point. Let's admit we love clothes and feel so keenly the idea that they are important, and a means of communicating, and who doesn't want to share the joy! Many have pointed out here the fallacies in this fantasy, and I'm chiming in with Pat late on this, but anyone who wants to share their wishful thinking and dreams here needs to be able to rely on being treated only with kindness! along with all the very useful doses of good advice everyone has shared.
PS I lovingly and enthusiastically asked my wife for shared lingerie days, but she refused. She did go through a short phase of saying that she was the owner of the right to fancy lingerie, and then bought some, but took it back- a combination of not feeling attractive enough, which I tried to rectify, but really just not wanting to remember that I would be wanting to wear it, which would completely ruin it for her. I am very very glad some members do have the fun of it, though. That helps me feel it wasn't a bad idea after all!
