Yep, pretty much.
“As the sociologist Michael Kimmel notes in his indispensable cultural history Manhood in America, men care a great deal about what other men think of them. In fact, he says, “In large part, it’s other men who are important to American men; [they] define their masculinity, not as much in relation to women, but in relation to one another. Masculinity is largely a homosocial enactment.”
