I'm sorry to say, but people could very well be noticing you. I get often stares nowadays in boy mode. Not all the time, but my body and appearance has changed in a big way. People notice and sometimes react openly. It depends on the people and the stares. Some look as though they are trying to figure out what's going on, some look at me annoyed and disapprovingly (I've gotten Ewwed at as well) some have a supportive smile and kind behavior, sometimes guys look at my body in interesting ways, etc. What I'm trying to say is that there are many reactions, but people will start to notice and act in different ways. I'm at the ambigious middle stage and it sort of sucks. If you are in the stage, be prepared for these various looks. It's an unfortunate part of the process, but most people have to go through this. Good luck and don't let people get to you. After all, it won't last forever.
