Why is it OK for women to gawk over men but not ok for a man to gawk over a woman?

First off, disclaimer: I know everyone has their own opinion and level of comfort in their relationship and that's ok! If you and your partner understand each other and agree on that, fine. Just don't be a hypocrite.

I am tired of seeing women complaining about their men looking at bikini models, celebrities, nudes, scrolling through a model's Instagram, and etc. But yet they are watching Magic Mike, following hot guys on Instagram, gawking over the newest shirtless celebrity photo......but a man has to hide these things from their significant other because the other isn't comfortable with it? I just don't get it. If you are complaining about your man looking at any of that, you too better be a saint. No I'm not accusing any woman who might be against their man looking at other woman, of looking at men as well..... I'm just saying I see it a lot where the guy has to be the one who drops all that stuff but the female does not. I feel like being attracted to others is part of being a human, it doesn't just go away when you get into a relationship or get married. You just have to handle it differently.

What are your thoughts?? Am I a horrible person for not caring if my husband finds another woman attractive? There are plenty of men I find attractive but doesn't mean I want them or love my husband any less. If anything I think it makes me love him more because he's mine, we are in this together, and to me he is very attractive.
