I think the most important thing men need to learn when navigating intimacy is how to deal with rejection. If men turn into monsters the moment they even feel rejected, women are not going to want to connect deeply with them. Meanwhile, the reality is that men often lack the empathy and emotional awareness to understand the context of a situation and why a woman is reacting the way she is. They might easily misconstrue as rejection what is simply a misunderstanding they've caused by not communicating, or withholding emotional engagement, or "trying to be cool" to the point where their seeming aloofness becomes a turnoff. Meanwhile, men are taught to leave it up to the woman to initiate a conversation about feelings, which means they have nowhere to go when they feel flooded or overwhelmed by their own emotions. These are all situations that can be dealt with through better self-awareness and greater relational skills. However, most men are so used to feeling victimized by romantic circumstances and overwhelmed by their own emotions that they never recognize that solutions exist.
