Answer:
This is a very hard to answer question because I don't know you personally but I will try the best I can. There can be many reasons why a seemingly perfect girl doesn't have a boyfriend. Maybe you need to just hang out with guys more, you need to have guy friends before you have a boyfriend. Try to smile at guys more(not creepy smiles just pretty pleasant ones), be more social with guys and when you find one you like, don't be afraid to flirt with him and talk to him. But most importantly: Take your time finding a boyfriend, usually the perfect guy will come out of nowhere when you least expect it.
also there is somthing called the friend zone where you are to freindly to everyone wich makes you seem less like the dating type
