Women for whatever reason have much more advanced social skills than men at most ages in our society, and are much more accepting of people without highly developed social skills as friends.

A bit of a tangent but women, and AFAB people in general, are probably better socialised because they have to have a good sense of solidarity to survive under patriarchy, similar to queer people. Women growing up generally form more emotionally open bonds with each other than men do with men. Women will walk each other home on nights out, ensure that their friends are safe, give each other a tampon and are generally more willing to help each other out than men are to help men out. Men don't fear being assaulted when they walk home to the same extent or for the same reasons women do, and are expected by other men to be able to defend themselves. So women form bonds out of necessity, for their safety under patriarchy (and obviously because they want friends), so they have more practice socialising. And of course, toxic masculinity plays a massive part in why men are not as good at making connections as women.

This is generalised and theoretical, and just comes from my experiences in life, but I think it definitely plays a part in why men struggle to socialise compared to women
