Very good topic there! Now, I am going to respond to a semi-random response in this thread, so sorry for breaking the structure a bit.
You make several points:
1. most advice on mental health/psychology out there seems to be female oriented;
2. culturally there seem to be issues with addressing men on these topics: both just addressing them might "seem to create a problem" and also they as "audience" would probably be in denial (or are supposed to be in denial?).
I think on both points and also some others you make (Peterson, etc.) you are partly right. But I also think these are distractions. In the first place men are human beings as are women. So whatever advice out there shall be tailored for both. Perhaps I am just lucky to be an environment where also men open up. Yes, it's true that more women around me go to see a therapist/psychologist than men (as I do), but I also sense plentiful interest from men around me in topics of psychology, mental health, overcoming anxieties, depressions, etc. What I am trying to say is this: yes, some groups of people around are less easily open about these topics, but I personally found that all are about equally sensitive. While I know many sensitive and deeply self-reflective men and women, I also happen to know men and women who are equally oblivious to all this stuff.
My take: forget about genders on this, target human beings with your thoughts on this. And if you decide to illustrate it with photos of men, kudos to you, a good choice there 🙂 .
