Surely? humans have evolved to witness and learn about the s*x act from birth onwards?

Question

i often wonder if there would be less screwed up people if this were so.

that is how u would learn about it 10,000 years ago if u lived in a cave

instead of discovering it accidentally , with accompanying embarrassment or from immature peers or exotic pornography

all (nearly) parents hide the act and whisper about it

Answer 1

You have it exactly backwards. All human cultures have s*x in more or less privacy, for the most part. Swinging is a Western " thing ", that is not all that prevalent. Even baboons go into the bushes. We are evolved more toward the private act of s*x, so please spare us any over reaching social engineering projects you were contemplating.

Answer 2

We have a screwy culture which has taught us the human body is shameful and s*x is not allowed. A lot of it in the US is a holdover from the days of the Puritans, who believed s*x was a sin; but much of it is also an attempt to protect the innocent people (children) from those who would show them things before they are prepared to know. (predators).
