Women look too. I've seen women holding hands with their significant other, their eyes wander (if only for a tiny little second) when I nice hunk passes by. I'm sure she's happy with her man, but still appreciative of attractiveness when she sees it.
Sometimes looking is just looking, not much can be done other than to minimize. I notice someone attractive and naturally I want to study their appearance briefly. They are pleasing to the eyes and an unexpected delight. However, this does not mean I am willing to jeopardize a committed relationship for someone I gazed at for a couple of seconds.
I also realize the same occurring with my own significant other. He looks for only a moment... and the thought passes.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
