Is it weird to have guys as friends if ur a girl?? PLEASE help!?

Okay some people laugh at me becuase at recess i only hang with the guys. Thats only because i dont want to waste my recess talking. I Play tag everyday at recess. My guy friend lets call him bob, called me one of his best friends once. That was kinda like cool. I have like 4 guy friends. Of course i dont hang out with them out side of school because it would kinda be weird. Anyway the point is, is it weird to have your ' best friend ' a guy if your a girl??
