Social conditioning sucks. Boys are taught that vulnerability and even showing any feelings other than anger are 'wrong'. they are taught to fear being less-than in any shape, way or form.
I know my husband suffers daily from how these messages kept him from reporting his abuses. Perps take advantage of the 'norms' boys are taught, and it keeps the culture alive and well. I can't stand it. My own son's peers and their families embrace these thoughts, and for me, it's a daily struggle to remind him that who he is is made up of all feelings. I want to make sure he has the safety that my husband (and I) didn't have at home. For me, not buying into the hyper-masculine BS is a part of creating that safety.
