"n-dimensional" That's a neat term. But how is it different from a set of discrete points along a continuum?

However, be that as it may, if you watched the National Geographic program on gender, you would be certain that gender is not, as their narrator put it, "binary". In fact, they discussed a group in India which is considered to be a "third Gender". Interestingly enough, this group was comprised of biological males dressing and acting as females. Are they cross dressing? I think so.

So, you raise a very good point. Is a genetic woman cross dressing in a dress? We would all say "no". Is a genetic man cross dressing in a dress? We would all say "yes". But these are extremes on a very familiar continuum. What about the points in between where the distinction between male and female is not so clear? What about an inter-sexed child (has both sex organs) who is raised as a girl; is she cross dressing in a dress? What if another inter-sexed child is raised as a boy but wears a dress?

What, then, is cross dressing? There was time when I thought I knew the answer. Now I am not so sure. Here is my best guess:

Teacher: Now, class, who can tell me what crossdressing is?

64 yr. old pupil: Cross dressing occurs when an individual, usually a male, wears clothing that is typical of a gender opposite that which he or she typically presents.

That definition is not objective by any means; it hinges upon the lifestyle of the individual. It says that, if you have spent your life primarily in drab, then when you wear a dress, you are cross dressing. On the other hand, if you are presenting as a woman 24/7 and have been doing so for such a long time that you have become totally accepted and identified as being a woman, then you are not cross dressing any longer.

So, that's my answer to the question. It is an excellent question. Thank you.
