Help! They think im gay...and im not?

I am the girliest boy at OLA! (except for one 6th grader but if I befriend him they'd think we're a couple) I like to hang out with girls, I get them better there not as stupid or playerish as the boys in my school. Now I do have many male friends. And what I did today didnt exactly disprove it, I wore a santa hat to my school and kept it on for the entire day.(it was a day for crazy hats) And this mean/semi butch chick wore one too. She kept on calling me gay and well everytime she did I just walked away with this sorta embarrist look on my face. And after school my bestfriend owen told me" get ready to be chased with that thing on your head" And im like 50% sure im not gay. Now im no homophobic, I'd be completely fine to have gay/lesbian/Bisexual/transexual friends and could accept myself if I was, but as I've stated im like 50% sure im not.
