Dont know if this isthe right subreddit to ask but wondering what is the age of males where females start to be catious around grown males? I read a reddit post where a few females in the comment section said they prefer males to be in front of them in yoga class where they can see them and not behind them. Made me wonder what age does fear of males start for women are they as cautious like this around teenage males and boys

Edit: I mean what age of (males) are viewed as a threat?
