This is true in some ways, but there is another side to this issue:
Plenty of men are seeking help, plenty of men are discussing emotions with friends.
The problem is that a) therapists and other mental health professionals are not always informed on men's issues, or do not know how to work with men in general because a big part of it was designed for womenand b) peers, including not just other men but women too, will ridicule men when they do express emotions.
In other words: there are men who are talking, speaking out, breaking these gender roles, but as a society we're not listening enough. I wish instead of focusing so much on getting men to talk about their feelings and more on us as a society creating an environment where it is safe for men to talk about their feelings. I dislike the individualistic approach some people (not saying you do this btw) have where they say stuff like 'men just need to express themselves more', because it makes it seem like its all the fault of their actions and not also society's reactions.
anyways here is a article on the topic of therapy for men: https://www.sbs.com.au/news/the-feed/article/high-therapy-dropout-rates-reveal-failure-to-connect-with-men-study-shows/ytmwmbjke
