Too intimidating?

im a teenage girl and ive never had a boyfriend. it feels like everyone around me has one currently or at least has had one before. none of the guys like me and i dont know what to do.

ive been told that alot of the guys in my school think im intimidating.

im not a typical teen girl i guess. im a smart ass first off. i study martial arts. i want to be in the air force or navy. then the fbi. and im what most people called ripped and stronger than almost all of the guys in my grade. im also a strong athlete. and i do real well in school.

on top of all this a guy that i was kind of "involved" with but never dated has been going around and spreading rumors about me and telling all the guys to stay away from me.

i get real upset because people are really mean to me about it. and i dont feel confident about myself sometimes and i dont feel pretty. i dont think im ugly but honestly, what do i know?

does anyone have any advice on how i could turn this around? or at least find a guy who didnt care that i could beat him up?
