Now accepting applications for Single, Straight males. Minimal experience: 1 year

I've recently realized that all the men I have knowingly attracted, can easily be placed into three sad categories.

1. Men of Questionable Orientation (MQOs). I don't know what it is but if a guy is possibly/probably gay, I somehow become the object of his hearts desire. This has been a trend since high school, when seemingly flamboyant boys became publicly interested in me. For some of them, who later came out of the closet, I think its all for show. They pick the girl least likely to go for them and "pine away" for her for years. But I still don't understand it. Is it me? Do I remind them of the ones they truly want to be with. Am I masculine in some unknown way? One thing for certain, MQOs are not good for the self-esteem.
   
2. The Taken. A more recent revelation are the guys with girlfriends. Maybe its the whole "grass is always greener on the other side" syndrome, but I appeal more to them than perfectly available boys. I don't play completely innocent on this one, I may have encouraged this a time or two, but I do not approve of cheaters. The good thing about this category, is that it can produce really great guys, although the very recent ex can be quite a problem. In fact, after breaking up with their respective girlfriends, my exboyfriend and ex-imaginary boyfriend started seeing me. The bad thing about this category is I fear that it has given me bad dating karma. And let's face it, in the world of dating, a girl needs all the good karma she can get.
3. The Never Been Had. By far the saddest and most predominate category, Never Been Hads are complete relationship virgins. These guys have never dated a girl, been intimate with a girl, or sometimes even talked to a girl in person. This also started in high school, when AIM conversations turned into flowers on my birthday and bad poetry in history class. Even now these guys are "dating" me without my knowledge, dishing to my closest friends that they like me, asking me out for coffee, but only over Facebook. Its all very middle school. I feel bad for these guys, but in no way do I ever want to date them. Never Been Hads may also give me bad karma as gently turning them down, or avoiding them altogether, is completely necessary.

My search continues for a man who is actually into girls, but only one at a time. One who has prior relationship experience, but is not hung up on these prior relationships. I swear asking for another category, one in which I am attracted to, is not too much to ask as I am not that picky. However, I fear this fabled hero is exactly that; completely fictional.
