Why don't men approach me or randomly flirt with me?

Adaire
I have been curious about this for awhile. I think that I am fairly good looking, probably more cute than hot. When I am out around town I never notice Men checking me out and I have never been randomly approached or asked out. Some of my girlfriends tell stories about how this happens to them all the time (and they are not extremely hot) and it makes me wonder. Am I putting off some type of vibe that makes Men avoid me or am I just an acquired taste in the looks department. I would love some honest opinions or suggestion on how to attract more attention from the opposite sex or appear more approachable.
