Any person who has a female body is a woman. But that is not all:
- She feels that she is a woman
- She thinks like a woman (whatever that is supposed to mean)
- She is attracted to men
The only complexity most people try to handle these days is item number 3: Sexual orientation. More and more seem to agree that same-sex sex is OK, and therefore add sexual orientation as a second dimension to the model.
Sexual orientation is by most considered binary, as well. There are those that are heterosexual and those that are homosexual. Bisexuals are often left out in the cold, in the same way many people find it hard to cope with people who do not clearly respect the sex divide. Children soon learn to search for subtle signs that can help them classify a person as a girl or a boy.
The everyday model conflates the biological sex and the cultural gender. I my language, Norwegian, we actually use the same word for both concepts: kjønn. That is: Language itself forces Norwegians to think of the two as one.
I use a very essayistic style in this blog, but sometimes it is useful to take a completely logical approach to typology and classifications. David/Davida, my fellow crossdreamer and author of Some Thoughts on Crossdressing, has developed a systematic classification of the various dimensions of sex, gender and sexuality, which I find very useful. He/she has given me permission to publish it here.
