I'd personally never date a guy I wasn't attracted to both physically and personality wise. If I like his personality, but I'm not physically attracted, that's the definition of a friend. As for the 3 most attractive qualities.
I think with guys, looks are important, but personality is key. I've been with guys who have amazing personalities that we both hit it off really well, but if they didn't have the personality I normally wouldn't have found them attractive.
I go for guys who have a great personality and who are intelligent, confident, witty. They also have to be able to handle my personality lol. They don't have to look like Adonis but I prefer a guy who cleans up well and takes care of himself.
Be clean, well groomed, and smell good. Girls appreciate that.
