I am told by many people including strangers around me that I'm pretty but why have I never gotten asked out? I'm 18 & have been single my whole life?

I get good grades, dress well and gets compliments daily about my outfit, people say I'm very kind and mature and have a bubbly attitude and I am social also but no one seems interested in me and I have never been asked out to go to a dance or a date :(( why is this? Would it be different in college?
