1. My right breast is smaller than my left 2. My right underarm grows significantly more hair than thel left Is there some reason for that?
I can't speak for your underarm hair. i have no idea about that. However, it is really super normal and totally common to have one breast larger than the other. I don't know why that happens, but it totally does. Can happen with feet too.
um huh, it seems genetic, i dont really think how you"look" can be classified as masculine or feminine
i guess it might (don't quote me too much on this), have to do something with the side you prefer. i know i hate the fact that my right bicep is bigger then my left one, but it's the right side i'm more dependent on. it's normal for your breast to be slighty larger then the other, and i've read that it's quite common for women in general. the hair might be a little strange on every parts on our body, so i can't say for sure. my left side of the face is more thicker then the right side when it comes to my beard. i guess it's just something natural that comes to me. no one really has an even side amount of thing. i hope this helps =P
I've always had a rather masculine amount of hair growing on me. I actually have a slight mustache, that started growing when I was still a kid. While, it might have something to do with your genetics, it could also be because of hormones.
