Hopefully we grow in our understanding of ourselves through time and by asking questions. With crossdressing the first serious question is "Why?" Why do I do this? It seems that after batting this one around for a time many of us move on after deciding "I don't know, it could be any one of a number of things but I do." Not the kind of thing that would make the scientific journals but a fairly common result.
So what was the second question you began to ask? "How far do I take this (or does it take me)?" "How do I control it?" "Where can I get help?" "Why do the sizes in skirts change so much from maker to maker?"
