I'm not sure the point is expression per se, or always being emotional, but rather being okay with introspecting on emotions when they do come up and more to the point, what's causing them.
I'd compare it to a tooth abscess. It's not like it's so painful you need to scream. It's just kind of there, occasionally causing problems. But if it goes untreated long enough, the bacteria in it can kill you. There are some parallels there with loneliness, which a lot of men suffer from.
So I'd say this is more the realization that "Oh, this pain is because of this source. I'm gonna go deal with that source." The process of dealing might involve making your emotions known (such as when breaking up).
Of course, if you're legitimately not in any kind of pain, then great. But most people are, in one form or another.
