As for being a 'big girl', eh, beauty knows no shape or size. Sure, the media can parade around their version all day, but it is seldom reality in either what women look like in general or what most men are looking for. It is also not always healthy. So you are taller than the others? Awesome. As Chris said, you stand out. You are not as graceful? That is arguable as we have seen you dance (you were not the one falling on your butt ) and heck, you can always make up in power and strength what the willowly types have in grace.
My exwife was 6' tall. She got all kinds of notice. She was a big girl. No two ways about it, but heck, it didn't stop her from being the center of attention.
