I need some help with my appearence i think...?

i dont know what to do anymore. every guy i ever talk to ends up thinking of me as just a friend. guys tell me im pretty and cute (never hot) all the time but yet i cant get a boyfriend? im really sporty compared to most of the girls at my school but not like a butch sporty. i can just follow sports and i play most of them. im 5'6" and have blonde hair which i straigten a lot. everyone tells me that im fun to be around yet ive never had a bf and im in high school. every guy just ends up being my best friend in the long run rather than their girl. im not a tom boy at all. idk i just want to know what i can do to make my self more attractive. and none of that be yourself crap cause thats not what im looking for lol idk maybe im just overthinking it. i just need hellpppp please:/
