Kate is, of course, correct that our chromosomes dictate how much femininety we have as individuals. I do go along with the prevailing theory
that for a few million men with that normal XY combination they do still react, sooner or later, to a "trigger" that sends them along the CD path. Why some possess that trigger reaction and others do not still has not been explained as it's not genetic. Feeling more or less masculine does not seem to be a factor. However the main reason that I responded to this particulat thread was Sherry's comment that since most men are straight they would not become cross dressers. Fact: Most, perhaps 85% of CDs, are heterosexual CDs. Not making a judgment of any kind in mentioning that point. We can only guess whether there are more homosexuals and bisexuals in our country than straight CDs but I know for sure that most gay men are only attracted to men with a very few interested in CDs. In that remaining roughly 15% of cross dressers there are many who are BI but very few that are 100% gay. Those who finally fully transition are not included for, after all, both their sex and gender have changed. Please do not try to interpret the above as being written by a sister who is afraid that they might be gay. I've passed that point some 40 years ago and now secure in my orientation.
