Some people are simply more flexible than others. I'm one of those who is... not. You remember those toe-touch tests in school, where you had to put your feet on a box, and reach for your toes, then your reach was measured?
Yeah, I could never even touch the box, much less my toes.
I wouldn't begin to speculate on your specific anatomical quirks, though. I would suggest asking a doctor. :)
If you want to improve flexibility, I would suggest yoga... it will improve your flexibility overall, and you'd be surprised how tightness in one place can affect other parts of your body.
