Everyone is different, but I rarely find other's wives attractive. (Partially because of the respect I have of their marital vows which are their's alone to break, if they wish.)
I find my wife attractive because of love and loyalty over everything else. Other than that, I only find women attractive for the most part if they are age 18 to 30, petite, small firm breasts, slim hips and small tight butt, and average to athletic in tone. I like girl next door cute, not overly model-like... and I hate big hair, and too much makeup.
