Why do single men fuckzone me?

Most people would describe me as very introverted and shy. I am not a flirtatious person and I dress modestly. A few men (college acquaintances, coworkers etc.) have expressed their interest in a fling but take no interest in getting to know me as a person. Some of them even dislike me and act rude while being nice and welcoming to everyone else.

I know these men have crushes on other women they want to have relationships with. What do these women have that I don't? Am I just not pretty or intelligent enough to be considered girlfriend material? I know I'm not acting needy because I was never expressed any romantic interest in these men. What do you think?
