Looks, whatever people may say DO matter. A guy could have an amazing personality, which is fine, but if he has a face like a back end of a bus, ain't happening. That said, we're all different, who I find gorgeous maybe someone else's Munster! lol
For any relationship to work there has to be at least some physical attraction, otherwise it's doomed from the start. Shallow I know but I firmly believe it's typical of human nature. Looks, smell, personality all attract us to a mate, it's how we're built, to deny that we do those things, even subconsciously, is naive.
