Can you guys out there honestly answer me? why do most guys i go out w/ always rely on looks?

i mean am i not pretty or something? i mean i think im pretty but not in the conceited, selfish bitchy way! i mean everyone at my school is like short and super skinny or tall and super skinny! i dont care what other people think of me i just want to know the truth! i mean im tall, about 5'7 have blue gray eyes with green and hazel in them, have porcelain skin and dirty blonde hair! im not your average girly girl either. i would prefer a pear of jeans to a skirt and would prefer black, purple or blue polish to any hot pink bublly ****! also i dont care about clothing companys ie: name brands. also i metal chick! ive been listening to it since i was 3 for ***** sake! so why is that every guy i come across always refers to me as a more of a friend type or that im not girly enough for them or some **** like im to guyish?! im still a ******* girl and i still have a chest! anways all im wondering is from hearing how i described myself would you guys all think the same? be truthful cause thats all im asking! :)
