I guess to really answer this question, you'd have to first decide what crossdressing means to you. For most of the contributers to this thread, it seems that crossdressing is part and parcel of who you are: A compulsion that drives you and is as much a part of you as your own flesh and bone. It truly IS a part of your overall personal make-up.
It might be easier for me to give it up, simply because, (at this point, anyway) it seems more like a hobby; a game; a way of dressing up for Halloween or playing at, "What if..."
At the same time, I don't know... Maybe I am just deceiving myself. Maybe deep down, I am just as driven, just as compelled, and crossdressing really IS a part of who I truly AM.
Pondering, pondering....
