Did your parents have sex around you as a child?
And if so, what (if any) effect has it had on you?
Is it weird/confusing/traumatic for children, or does it provide a healthier and more realistic model of sexuality than pornography and school-based sex education?
Both of those first two studies (the third one is not a study) say that there’s actually not a significant harm, especially just for nudity.
Not to mention the fact that they’re both really old (pre-2000) and based on data collected from the 1970s to the 1990s and pre-date home internet access and only from data collected in the US(actually only in 3 cities in California)
