How easily are weak males emasculated, even if the wind blows a little too hard near their nether regions, their T levels start dropping. Yaahuuu
This is how normal couples interact with each other, guaranteed his ego gets boosted when his wife shows she doesn't want to share him.
The truth is that men would get upset if their wives didn't care about polygamy, because they want women crying and fighting over them. Newsflash; if a woman doesn't care who you marry, she isn't really into you. Even the Prophet SAW's wives would get jealous.
