how come with humans, people need to know and be taught how to have sex and what exactly to do. Like having sex is putting a penis inside a vagina. I didnt know that. I used to think that laying on top of someone counted as having sex or something like that. I didmt know a certain specific act was needed to reproduce. But how do animals know how to have sex without anyone teaching them or giving them instructions on how to do it like the way humans need it? Its like being born knowing how to drive.
Update: its like being born knowing how to drive a car, fly an airplane and talk!
