Carla,
Over time I have leaned one way or the other to some degree, but having gone out many times in recent years it boils down to this. I almost become another person when I go out. I turn into a much more outgoing person and the experiences related to being this different person sort of became addictive. It is hard for me to comprehend why that is. I do not think I would want to do it all the time though, so I guess that firmly plants me in the crossdresser check box. I think partly I missed out on a lot of fun activities like dancing etc when I was young due to being so shy. Funny how my Sandi personally is WAY different. So the short answer, I do it for the fun and excitement but for me , fun means I have to interact with others. Dressing up just for myself does little for me.
