I've been told (by men) that men are taught by society (patriarchal culture) to view their personal value interms of their partners. It's very objectification in my opinion. But apparently men are taught that their self worth is defined by the number of women, or the attractiveness of them women who chose to date them. Then men take rejection personally, as they have less self-worth or not enough if they are rejected by a woman. This again is toxic and is an example of how patriarchy is bad for men. People should be allowed to chose who they want, without others taking it so personally.
I hope men can learn that they have inherit value as simply being themselves, and don't need women to validate their self worth.
