I'm sure I'm not the only one who feels this way, although I don't think anybody else has responded to this thread the way I'm about to. So ... just to add to the diversity, here goes.
For me, crossdressing was always an intensely sexual experience. I'm not a transsexual; I don't want to really be female. When I take on my female identity by dressing up, it's always important to me to try to be sexually appealing. There's a vicarious element to this: I'm becoming, on a temporary basis, the kind of woman who appeals to me in a blatantly carnal way. I enjoy her sexuality, and even while I'm inside that female identity, I still am observing her from a male point of view and being turned on by her femaleness. And if some other male sees her and is turned on by her, I get a thrill out of that too.
When I see pictures of a hot-looking sister on this site, my visceral response, whether she is a crossdresser or a transsexual, is as if she were a GG. And, like some other observers here, I also sometimes have a touch of envy that she can look so good, or curiosity about the skills and techniques that she uses to look so good.
