How many times do people have sex without producing a baby? It depends, but generally the answer is a lot. Maybe a thousand times to the one time resulting in a baby. And most people act like they’d have more sex if were available. Otherwise, the porn and romance (novel) industries would be much smaller.
Countries with lower quality Sex Ed tend to have more unwanted pregnancies. In Mexico, for example, I see lots of teens become pregnant earlier than I imagine they’d really like to. I’m not certain what the Sex Ed is like in Mexico, but my Mexican friends have told me it’s very limited.
I’m more acquainted with what happens in the US where “Reproductive education”often is the stand in for real “Sex education.” Someone said the way Sex Ed is usually taught in the US is like teaching “How an internal combustion engine works” and calling it “Driver’s Ed.” You’ll get a feel for how a car engine works, but you won’t know about stopping, signaling, or any of the concepts you need to actually drive a car.
In a Gallup pole on happiness, there’re questions concerning a person’s perceived freedom to make life choices. Having kids before you want kids is one big factor restricting someone’s life choices.
The US recently finished 13th in the ranking of happiest nations. I’d bet that Americans who had kids because they didn’t get proper sex education wind up with a more negative outlook about their lives, and help to drive down the ranking for the US.
