What do women think?

The other night, out of the blue, my fiancee asked me to put her thong on. I said no, but the more I resisted, the more she asked and just wouldnt let it go. So I finally gave in and put them on for her. I have to admit that it felt totally different from wearing boxers. I really liked the texture of them and the way they felt to wear, but I am embared to admit it to her. I kind of want to do it again, but what do I say to her? Can any women out there tell me if this kind of thing is ok from a woman's standpoint?
