I guess that would depend on what is meant by "come out". I first wanted to wear lingerie when I was a kid back in the mid '60, but had no thoughts about being the wrong sex until a few years later. The first person I came out to was my then girlfriend, later wife, who I told I liked to wear pantyhose & stockings. After we split, I joined a club for cross dressers and, of course, there was no hiding from them. A few years prior to that time, I stopped worrying about openly buying lingerie & hosiery for myself. These days, I wear a bra & pantyhose, including with shorts, daily. I also wear nail polish openly. So, there are many steps along the path of coming out and no single "magic moment".
