I've had that discussion before.

Gender roles, and thus gender presentation, are cultural for the most part. Some are common enough to multiple cultures that it approaches being just human culture.

But even in western (us, canada, europe) cultures, there have been periods where the presentation of masculinity would be considered feminine in other eras. So gender roles & presentation aren't fixed in a given culture.

If I, regardless of what my genitals are, present as a man, then I am effectively the same as whatever a man is in my culture. If that also includes taking on the gender roles of "man", then that's another layer.

However, this also means that when enough men shift their presentation and roles, anyone holding to the previous roles and presentation are now "less" a man in the cultural sense. It really, truly is a majority rules situation, and the minority are what get relabeled (usually).

The more men that reject an arbitrary paradigm of masculinity, the more we shift to an open, loose definition of what is and isn't masculine, with the eventual possibility that gender becomes so loose in definition that masculine and feminine become irrelevant terms, if the labels also lose relevance to the majority. And I believe that if enough people reject fixed gender paradigms, the terms would inevitably cease to matter.

I mean, we've already started to add qualifiers. We have traditional gender roles as a specific thing as separate from current gender roles.

This isn't to deny that hormones and genetics will push people into behaviors that are linked to gender because they're mostly linked to sex. But even with those pressures, we usually have room how we express those behaviors.

It's why I always tell folks, particularly younger folks, to not worry much about labels. Be who you are, as long as who you are isn't a douche, and you'll eventually find the labels that feel right. And there's a good chance you'll end up shifting your self over time anyway, which is fine. As long as you don't fixate on labels as defining the person, the self, you can freely shift labels as the self shifts. It's when you pick a label and think that you have to fit it in all ways, forever, that you run into trouble.

So, fuck yeah. If you feel "girly", be girly. Enjoy that shit. Be your best self. It'll eventually work out :)
