how important is physical attraction?

I'm involved with a man who really likes me. He is kind and attentive, we have activities in common,and values and temperaments that are compatible too. He's a good guy/ But there are certain physical things about him that turn me off a little. I know that no one is perfect. I certainly am not. And as we get older, physical appearances, for men and women just aren't what they were... and there are probably things about me that he may have to overlook too.
It's just hard for me. I really have to work on convincing myself to look at his heart, the way I'd want a man to look at me too.
I've been with men that I just adore that have been overweight for example, and I couldn't care less, or have other physical flaws. It just worries me that something is missing that I can't overlook his.
As we get older, we also have less choices, less people that are available and interested in doing the same things...at least that's how it is in my experience. I know I need to find someone that I enjoy talking to, someone that I trust etc....how important is it that I enjoy looking at them too? Or maybe that will just come after time?
please let me know what you advise. thanks.
