From what I understand, loveuality is more of a fluid understanding of one's own desire. Once someone knows what loveuality is all about, they can easily and sometime distressingly figure out their own loveuality, at any age. When someone tells me that they are straight/biloveual/gay, I take it as the fact that the primary amount of their feelings are towards the opposite/both/the same gender(s). I never take it as what they are, but rather how they feel.
For example, I identify as being gay, but I have felt physically and emotionally attracted to other women. They were few and far between, so that is why I still say that I am gay.
As for the flamboyant people, I find them irritating. Not because of the fact that they are flamboyant, but rather because their personality does not coincide with my own. They are often very loud and outgoing, while I am reserved and cautious.
