People have their preferences, what is one to do about it? I think what we would like is people to look beyond that stuff and like/love us for us (but that sort of begs the question, who are you? Our phsyical appearance is a part of us, as much as our political views.); but, it takes two to tango. I've got my preferences.
Interestingly enough for me, attraction has many times grown on me. A couple of women I was with, I was not really attracted to at all, at first; but, then I grew into them such that, they seemed my physical ideal. I think if I tried to force that reaction, it would backfire, but it happens naturally some times.
Probably there are folks who are wiser, and less vain, and work on the acquired taste principle; and, it probably works out better for them. There are only so many dark tall and hansoms, and buxom babes out there; and most of them are out of 99% of everyone else's league anyway. And most of them are probably a bit dense, shallow, and callous anyway.
Beauty is in the eye of the beholder. On the one hand, I think, being honest about your preferences and sticking to them, there is something to be said for that. I think there is also something to be said for, trying something new and giving it a chance. I just worry, what if you give it a chance and you find out you just don't like it. Or, what if you stick to your preferences and end up missing out on what could have been the best thing.
I think physical appearance just happens to, more often than not, be the first impression. You could be attracted to some one who is absolutely stunning; but, perhaps they are also a selfish cheat, self-centered, or have this or that problem. So, I think we some times end up throwing the baby out with the bath water; and then, we buy the nice house with the massive crack in it's foundation.
Life is ever ready to bewilder...
