If I am so beautiful, than Why don't guys approach me?

All my friends are happily married or in engaged or in a close knit relationship with amazing men. The thing is- I'm still single. I haven't had a boyfriend since I was 13! Everyone says I'm beautiful, attractive, and sweet but there's so, etching different about me. The fact that I'm "elegant" and I come off as a hmmm how can I say it, "high and mighty"? But I, not stuck up and I don't think I'm better than everyone. I'm always happy and smiling and being friendly. Everyone says guys are scared to approach me but why? Is it he fact that I'm "too feminine" do I need to change that?
