I rely on biology.
During sex, there is always a passive part (which is feminine) and an active part (which is masculine).
If there were not such a pattern, we wouldn't be such an overpopulated world...
I mean ...it means that heterosexual intercourse is extremely predominant.
Okay first of all, biology itself has long made the distinction between sex and gender. That is the study of human biology making that distinction. Like actual biologists, genologists and actual medical personnel. Science doesn’t magically change when it travels overseas. It’s just the observance and reporting of reality. Granted the translations might be a bit wonky sometimes.
Now Gender specifically refers to the cultural expressions for what is considered and expected from the feminine and masculine “norms” our species has come up with over the centuries. This differs culture to culture and has changed dramatically over the centuries
Indeed the idea of the passive part of sex being feminine and the active part being masculine (I’m assuming you’re referring to sexual intercourse/interplay) is entirely a cultural idea. Ironically enough
One that again differs throughout history and across cultures.
(Also, I don’t think this holds up too well in BDSM communities very cleanly, if you catch my drift? Just saying lol.)
It also sounds like very outdated and long discredited psychology. Just an observation.
Biology itself also makes it clear that the distribution of sex characteristics in the human species is through bimodal means.
Basically two “main outcomes” but a spectrum of potential outcomes in between.
(Apologies for my sloppy phrasing, I’m trying to be as simple as I can.)
Also I’m pretty sure our species is only “overpopulated” in the sense that we dramatically outnumber our resources. We’re not like actually overpopulated in the sense that there’s literally too many of us. But that could be outdated data I’m working from. Apologies if that’s the case.
That said, I totally disagree with the drift that the US is going through: in the US gender has become a social construct based upon stereotypes.
In my country gender is based upon sex and biology.
I can kind of agree with you that US culture seems overly reliant on gender stereotypes. But I’m not American so I don’t know for sure.
In my country, we actually bother to listen to those who study this phenomenon for a living. And my country is dumb as dogbones lol
Gender is based on sex and biology insofar as such factors can obviously inform such expressions and identity in individuals.
That might not always line up exactly though. Much like the distribution of sex characteristics.
So sayeth actual Biology
Again such a phenomenon doesn’t magically change over borders. Science remains the same.
