"Why don't men talk about their feelings?"
Because if you do so you will be dropped by your partner. That or she'll just be fucking other guys without telling you.

Women have no time for what they perceive as weak men. It's a natural reaction for them to be repulsed. You have to take everything and smile, because although you are "equal" today, you aren't really. It's still your job to be stoic as a man as that is what she expects. "Have your cake and eat it too" as they say, the male partner must both look like a man out of a Netflix series and maintain all of the stoicism and male traits of his predecessors. Somehow you must be able to dress him, command him like a dog, but he still has to be independent and strong so you still maintain respect for him. Somehow.
