Have you guys heard of 'toxic masculinity'?
I'm not sure if this article will hit home with you:

Toxic masculinity, as I understand it, is what we as a society think a man SHOULD be, regardless of what he actually is. Men are expected to not feel pain, to be angry rather than upset if something goes wrong, to always be assertive or even aggressive (but never passive), to be strong physically and mentally, to not need to talk about emotions, to make the first move when it comes to dating, to be a provider and defender of the family, to have good sperm and always want to have sex, etc... basically, everything you think a man (but not a woman) should be, that's probably toxic masculinity. They are unfair standards to hold yourselves to.
The truth is, everyone is different. And it is possible for men to feel pain, and it's utterly ridiculous that you've been raised to feel shame about expressing difficult emotions. This may be why men are more likely to kill themselves than women are - because men are much less likely to talk out their emotions.
You might be typically 'masculine' in some ways, and not in others. And that's ok. You are just as valuable as a human being as you would otherwise be.
If you google it, you might find stuff about the patriarchy and rape culture, and that's worth a read if you care about women. Otherwise, the concept of toxic masculinity is really worth looking into in regards to self esteem.
