Men and women are wired differently from each other and women produce a lot oxytocin than men do.

about men's brains may not being wired for much connection
"A 2014 study found that males had stronger neural connections in the parts of the brain responsible for perception and action, while females had better connectivity along the neural pathways linking analytics to intuition — two areas used heavily in interpersonal connection.
Before this study, differences in these kinds of neural pathways had never been highlighted among such a large sample size (949 individuals)."
Here's an article that also talks about the study: https://www.pnas.org/content/111/2/823
Here's a quote from this article https://www.deseret.com/2015/4/21/20563175/the-difference-between-male-and-female-friendships#when-it-comes-to-building-friendships-men-are-more-likely-to-return-to-their-clique-y-roots-than-women-according-to-a-recent-study-published-in-the-journal-plos-one:
"So why are men and women different in the way they make friends? One hypothesis is the difference between the male and female brain.
Typically, women tend to have a larger deep limbic system than their male counterparts. The limbic system is a network of nerves in the brain connected to instinct and mood. The limbic system controls basic emotions such as happiness and fear. Because this system tends to be larger in women, females are more in touch with their feelings and have an increased ability to connect individually with others."
Because of women being more emotional and more affectionate than men are, and women being able to connect a lot better with other women than they do with men or men with men, wouldn't that mean that men and women are not very compatible with each other?
