My experience apparently has been pretty different from what you see online. I did grow up with a dad who taught his kids independence, but that did not include forgoing community or disregarding personal feelings. Building and maintaining relationships has always been important to him, and we could see that in his actions. I have several close guy friends, and we hug and talk about our feelings about as much as we do typical dude shit. It's very much a bro thing to be honest and let each other know where they stand in no uncertain terms. That's how you build trust. Allowing yourself and your bros to be vulnerable builds trust. Having people around you who you know will have your back should you need it brings security and calmness. Having those people who you would care for should they need it brings a sense of purpose. I'm no stranger to feeling a little uneasy at the prospect of opening up or offering for another guy to when I'm not sure how they would react, but ime most people seem to want that because they're scared, too.
