I don't know. I can't think of any male whom I have specifically appreciated solely for his physical appearance. I can look at a guy and admit objectively that he is symmetrical, pleasant-looking, etc. I wouldn't say I feel an attraction to him at that point.
When I notice a person, I begin to formulate my own idea of what they must be like beyond the surface, and by then then I've begun to form an emotional attachment to the idea of them. (I find this a little shallow in itself because the idea I have of them can usually only be based on a book I saw them reading or the kinds of clothes they wear or how they speak to others or something of the sort.)
As as [MENTION=3380]NuthatchXi[/MENTION]; mentioned, the behavior of the person always changes things. If I see someone I was previously attracted to behaving rudely, for example, I'm no longer interested on any level. On the other hand, if I see someone I was not previously all that impressed with reading a book I really love and writing in the margins of it or something, then, yeah, I'll jump to a new conclusion and have this new-found interest, and I'll usually find them more physically attractive.
It's just difficult for me to separate the sensory from the emotional, I guess.
I wrote the above response after reading the rest of the replies in this thread. I initially interpreted the question a bit differently. I thought we were being asked, like, if we'd ever been in a relationship with someone and never gotten over how beautiful they were no matter how many times we saw them. Something like that. (There is something like that mentioned in one of the Twilight books... Bella thinks she'll eventually get used to Edward's physical appearance but comments that she never does. And there are theories that humans are very into visual novelty.)
I don't feel like I, personally, ever get over stuff like that. But I really don't know...
