Here is a story about a boy (in the UK), at age 3, wanting to be a girl. This is purportedly an example of "gender identity disorder" rather than homosexuality. But he/she is remarkably young. The UK National Health system backed the child and parents' decision for the boy to live as a girl, when he was 4. She is now 5.

What has that to do with what we are talking about. The analyzing of relationships with others is different than what a person feels it right about themselves. Many adults can't decide on how they feel about others and can still wear the clothes that they are comfortable in.
Wu, the topic that you started is titled "At what age is a person aware of their sexuality". I just offered an article that seemed to be at least partially relevant to that topic. If a person feels that they are of the opposite gender, I assume they will be attracted to members of their own gender, at some point. Perhaps that is not always a safe assumption, e.g. as if someone were to feel that they are a lesbian trapped in a man's body. (I always thought that line was a joke. But who knows?)
Dude I thank you for the effort but I've wanted to be female all my life and have never thought about even hugging another guy. What you feel about yourself is internal. What you feel about others is external. I wish my parents would have let me try out of existence of being female. It would have lead me more quickly to the decision of who I really am. I use the term existence because when you feel internally not the way you look externally both sexes are with you, but they feel more like a disembodied soul that you can put on and take off.
As for men, I don't know if I've ever had any genuine feelings for any man. It's like they are just there and you have to deal with their imbecilic macho persona. Some are alright, but they have the communicative skills of a quadriplegic deaf mute. I can ask a women a question and get more information on everything about the subject in 5 seconds than I can in a man in 5 hours.
I guess if I'd went the way of the scalpel I could have had myself carved and injected myself into the image of a women, but that, to me would constitute being a fraud. Being a women is much more than just the looks. It is the experience of growing up a little girl and having that relationship with your dad as so many born into that status. It's the precious years of building up friendships with other little girls that would last a lifetime and allow the experiences of a girls night out.
As you can see I know a little about the scenario you've posted to address my topic. I'm fairly certain I can honestly say that the personal desire to be something you weren't born as and the art of affection to others are fairly far apart.
