Anonymous faces

Sometimes I come along faces on the web that I really love. See some samples below. I don't know what it is that I like, they can be young, old, rugged, fresh or whatever but I just can't take my eyes of them.

This guy is just plain sexy. Do I have a fetish for young guys with caps?

A little rugged but OH so sexy.

This guy is not really my type but there is something with
the look he has when taking the photo.
