There are also a couple of other things about her that play into this, and I think it's just a case of classic self esteem. She used to be VERY over weight. She's tall, too, and while now she's not over weight, she's still a big girl. My bro is also her first boyfriend. When we all first met her, she was VERY shy. She's still going to a JC, and doesn't really know what she wants to do when she "grows up." So, I think that a lot plays into it here.
