Depends on where you live I guess. One of my friends at Uni grew up in quite a posh area and went to an all-boys grammar school, but I’m pretty sure mixed-sex is the norm. I mean my first ever friend in primary school was a girl, it’s just that all the ones after that were boys and I just stuck with male friends after that. Doesn’t help that I started getting crushes on the girls in class when puberty hit so it was even harder to approach them normally
you forgot to mention the fact that all most all secondary schools here are single sex.
I barely talked to post puberty women at all until i was in my late teens
you miss out on a lot of primary socialisation in that kind of environment
