I have a female friend who said that no matter what women say, they do secretly look for a physically attractive guy...that's why most won't reply to messages sent. Of course, there are exceptions and physical attraction is subjective. This is according to her. Don't shoot the messenger! :)
I'm not sure what your friend's definition of "physically attractive." A person who takes care of themselves is "physically attractive" to me. That does not mean they have to be a model. I do agree that physical attraction is subjective. A person's character makes them attractive to me and I bet that is the case with most women. I do agree that chemistry is very important.
