It depends on the situation for me.
If a woman is interested in me, then I will go after her, it doesn't matter what she looks like in the attraction scale. If a woman is attracted to me, I want to find out more about her so I will spend more time with her, find out why she finds me attractive, maybe see if I wind up finding her attractive too and how we'd do dating.
Second, if no woman is attracted to me and I'm on the look out myself, I tend to go after women who I deem to be about the same in attraction level as me or a little bit less attractive.
I shy away from women who I think to be extremely attractive (without knowing who they are), the ones that are just attractive physically. Now if that woman is attracted to me, I'll still do the above aforementioned, but if it's just me trying to choose who to pursue, then it will not be the attractive one.
I don't feel good about it because chances are there are reasons why I find her to be attractive besides just her looks. Such as, she is easy to have a conversation with, has the same interests, etc etc.
But I just can't get over the "she's-too-attractive-for-me" thing. I hope someday I will, but as of right now, my 22 year old self cannot do it.
I also tend to shy away from attractive women because I'm convinced once I get in a relationship with them, they'll cheat on me at some point.
I mean I feel that way with all women, but the paranoia is more so with attractive ones.
It probably has something to do with the fact that I've been cheated on in all of my relationships except two.
