@Lordyaswas,
Dear god, give her an answer.
How on earth is he meant to be attracted to you if he's not attracted to women in general? Do you seriously think that once a man marries that his appreciation for women's beauty somehow switches itself off? And do you think that by finding something beautiful, he won't find you beautiful too?
As a personal thing, it's disrespectful to look at other women's bodies while your wife is present - if she finds it so (most do, but there are exceptions). Have you told him you don't like him doing it?
