Huh, I must say that this thread came as a bit of a surprise. I'm full out INFJ, yet I'm probably the furthest thing you'll ever find from a girly girl. I've been an huge tom boy since day one, was regularly mistaken as a guy all throughout middle school, and now in college I've been called the most "gender-neutral" person in the world on more than one occasion (not something I'm proud of, but alas). Everyone was always waiting for me to get beyond the "phase" and blossom into the traditional miss priss throughout my childhood, but that never happened. I never wear dresses, I never wear makeup, my attire consists of black t-shirts, black jeans, and converse. I used to skateboard religiously, I used to practice martial arts (and still would had I not developed breathing issues), I play guitar, I don't like shopping, and I've never been fond of chick flicks/overtly sappy love stories. I love kids, but I've never felt a "motherly" bond or desire to form such.
That being said, I wouldn't really coin myself as masculine either. All my friends are girls, I move like a cat, and my thought process and emotions are very feminine. I'm just me, I fit no gender roles.
