Why do girls always look at me passionatly?

yea its not really a common situation..or is it??
im 16.i remember that ever since 5th grade girls have
been the people that liked me.And what i dont understand is that
these girls are pretty,and i always catch them looking at me or staring
at me for a while.im used to it.im 5'7 tall athletic,..ppl have told me that i have a pretty face.im a nice girl to hang around with..but the reason that i dont why??? i dont get annoyed by that but what... maybe they like me? are they into me?

Well i must ask if you are interested in any if these girls that look at you so passionately? but well there may be some that like you or it may be that you may be mixing this up with a common glance smile (sometimes when someone looks at me while walking by i give them a polite smile that i guess could look like " hey there ;) ) or it could be that they may just want to say hey im nice and your cool so we could be friends if that makes sense
