Advice?

My husband and i have been fighting over dumb things like me calling him out when he’s looking at a girls ass or her breasts. Even when we dated he did so, didnt try to be discreet whatsoever just plain did it with no shame. There was a time i called him out on it he said “im a guy right? and men will be men”

Almost 6 years later and we’re dealing with the same thing. I feel more insecure now that ive had a child. I feel like every time i notice he does so its great looking girls who seem to have a nice big butt or breasts. Mine dropped after our son, and i have somewhat of a mommy pouch, my thighs got big and my butt seems to have flattened :(

I know i need to start working out, i used to before i met him and was pretty fit and toned. After we started living together it decreased and i gained some weight, not too much though. Fast forward some years.. i became pregnant and gained 30lbs during the pregnancy. Lost some after with breastfeeding and all but its come back on being at home and not working. Like i said, i know i need to get on it now. To feel better and look better, not much for him to notice me and to least think he’ll stop doing what he does. After all men will be men and notice something pretty walk by.

But.. what could i tell him? Ive tried explaining how it makes me feel but it makes no difference. If anything he’ll say something like “when was the last time i did so?” Which is funny bc I obviously dont call him out all the time so he thinks i dont notice only bc i keep it to myself at times. I guess what really bothers me is that he does it so blatantly. Idk... i just want to hear thoughts. I know i cant make him stop starring or keep him from looking obviously, lol
