17 years old and never had a boyfriend.?

I'm a 17 year old girl that's never had a boyfriend. I'm a bit shy, but used to be shyer and am coming out of my shell especially recently. I have curly brown hair and am 5 foot and green eyes and am not skinny but not fat. I have womanly curves. You know, if looks matter. That I know of, I've never had a boy like me. Like, I think this guy at school likes me, but am not sure. So yeah. Should I do something to get a bf? If so what? Thanks for any advice or positive comments=)
