Please help! It's really important!!?

I've never had a real boyfriend. I'm seventeen, I've had hook ups with guys before but that's basically it. At school everyone guys an girls tell me how nice I am an that I'm such a good person. They also tell me how I'm pretty. Girls tell me they can't beleive I'm single because I seem like I'd always have a boyfriend, since guy flirt and stare at me all the time. With all this, why wouldn't I have a boyfriend? Is my tome just going to be in college?
