Back when my ex and I first got together, we had a regular bedroom game in which she would help me crossdress and we would go out for a 'ladies night' on the town. Later, as my crossdressing became more practiced and sophisticated, I suspect she became more and more insecure as her own natural physical appearance radically and rapidly changed. I knew the turning point came when she objected about my legs and chest being shaved because she didn't like having sex with a 'pre-pubescent boy'. And so, that's how crossdressing eventually turned 180 degrees into DADT until we finally split.
