Society place expectations on gender roles and tend to feel alienated when these expectations are not met. Boys are meant to be dirty, rough, like sports and play with their GI Joes while arguing they're action figures instead of dolls. Girls are expected to be clean, fancy, better mannered than the boys and like dresses and barbie dolls. There's nothing wrong with those who do meet these expectations, but they're also nothing wrong with those that don't because at the end of the day we are individuals with individuals likes and dislikes and gender cannot be so easily defined by these expectations, or even your anatomy.

It's possible you could be transgender, personally identifying as a male while physically being born female. I can't say. I can count on one hand the number of transgender people I've actually talked about on the subject and admittedly know very little. On the flip side you could just be a tomboy. I've felt a stronger connection with the female gender than I have with my own. It's especially shown with how well I written for female characters and how many people have commented that I come across as a female with just the way I express myself. I even like to have a good cry when I'm feeling sad, runny nose notwithstanding, and I'm not ashamed to admit that. I agree with ringtailcat, just be you.
