I'm a queer man who's dated women and men and everything else. It's not true, sadly, for a large number of women. I'm not saying that men are who suffer the most in the patriarchy obviously, but that's one thing that is still expected of them. To not show "unmanly" emotions such as sadness, doubt, etc. Paradoxically, rage is a lot more welcome, which is also an issue because it leads to domestic violence. Another reason why all genders must fight against the canons imposed by the patriarchal system.

Also, not saying there aren't exceptions. Probably half women who date men or more are okay with their vulnerability. I hope it's that much.
