The default human development is female. At every development point of which there are several if that extra little bit isn't there, the body will develop as female. You you look at some of the pictures the FTMs post, you will find they develop pretty masculine and that's most likely what will happen to you if T isn't blocked. It's possible that your hormone levels are low or you might have intersex characteristics and that's why you haven't hit puberty yet. If these feelings came to you after you were in your teens, you are already producing male hormones in quantity and your emotions were the first to be affected.
In short, a child who fails to produce T will appear feminine. Give that child (male or female) T and they will develop masculine features. This is the reason I push so hard to get medical treatment for you. The more you delay treatment, the more you will have to overcome when you are older and it isn't fun.
