- Sex- depends on what you mean, but if not physically having it with someone, this is your sexual orientation. This does not usually become prevalent until puberty starts.
- Genitalia-Not your sex, no matter what people say. The correct term is genitalia and it refers to what you are born with. You don't hear them say, "This child has ambiguous sex." Do you?
- Gender-Who you are. What you feel. Your gender is what your soul deems you to be (Trinity's words) and if your soul says, "I am a girl" or "I am a boy" then that's what you follow. In other words, the soul trumps the genitalia and sex doesn't matter until you're old enough for it to do so.
