I think there is a lot you can about side-effects on anti-conception (from condoms are a hassle to pills mess with hormones), but lately young people are more in favour of ‘natural sex’ such as you pulling out early when the woman is ovulating which is (obviously) far less effictive. But the thing is,

one should always consider both benefits and risks.

young people aren’t good at considering the the results of those results because a) their brain is still developing and b) experience comes from trying. They need to be protected against themselves, just like we do with alcohol, drugs, driving etc.
