Yup - HATE it!
I think a lot of us know from fairly early on what we are, even if we didn't know the proper terms or names. Early on, a boys body is not significantly different from a girls (with one notable exception of course). We started out with slim bodies like yours, with fine and soft body hair like yours, with a voice like yours . . .
So imagine how it feels to be one of us and then one day your voice goes deep and you suddenly have dark, coarse, and heavy hair sprouting all over your body.
Yup . . . HATE it . . .
