> Well okay, say on grace, when it comes "your time" to watch "sexual perversions", who and on what basis establishes this time?

One day I got a topic on a forum, a woman wrote, say, a seven-year-old daughter asks where the children come from, and what uncles and uncles in the movies do when they first kiss for a long time, and then immediately naked in bed, what to say to her. And there, as an argument against the fearlessness and not telling anything, someone told the story of his aunt, who got married immediately after school (the 60s), knowing only that the children are growing in the belly, and when the husband in the first wedding night began to... go, did not take what he needed. And when her husband explained, so to speak, the essence and mechanism of the process, she experienced a real shock.
Obviously, yes
