IIN I can’t talk with boys

I can't confuse someone into liking men. The reality is that he likes to be around women and likes what they like. He doesn't like what the boys like. The only advice I can give him is to stop caring about whether the people you interact with are male or female. He could have just made a mental barrier between himself and other guys, perhaps the girls he hangs out with have instilled their way of thinking into him. If he has a genuine interest, but an inability, in making male friends, he's going to have to deconstruct the reasons. You either accept something about yourself and work with it or you change it. From what I've read, he's not putting a genuine effort into either. He should still lift weights, though. Strong people are harder to kill than weak people and are more useful in general.
