Why when the controversy of men looking at womens is women looking at mens crothces brought up?

Personally I think the two are of two very diffrent nature. Men have their reproductive organs and women have theirs so why are s thrown into this catagory. Personally from my standpoint when a man looks at womens it is the equivalent of woman looking at mans pecs or abs. I say this because the are not a reproductive organ and they show a womens femininity the same as a mans muscles show his masculinity. To me show a girls feminen beauty in a nonperverted way. I am just curious how other people view this issue.
