Definitely a tomboy growing up. Nowadays, still a tomboy, but with feminine flairs (in dress, makeup, etc.)
The culture didn't really have an impact on me as far as that goes. I had an older brother (2 years older) and only boys came outside in my neighborhood (girls rarely came out). I pretty much followed my bro around, so I was out there with them playing basketball and football (touch and tackle xD) and inside with them playing video games (not that video-game-playing dictates tomboyishness). Also, I was country as hell growing up and enjoyed being outside in general, roughhousing and whatnot.
But yeah, having an older brother and wanting to do what he was doing influenced me more than any overarching cultural influences.
