Our children are sexually active. They are making decisions that can affect the rest of their lives. They should be able to choose responsibly and be well-informed about the likely outcomes. They should know about sources of free or cheap contraception, who to turn to when pregnant or if they suspect they have a venereal disease, how to use contraception to avoid both, and, contrary to the impression of abolitionists, they should be told the benefits of abstinence. How can you tell people about that if you refuse to discuss sex? How can you imagine they will take you seriously if you turn a blind eye to something so many of their peers are doing?  They need an external source of support to resist peer pressure, and have sex later rather than sooner: lamentably, it is presumed amongst many young people that having unprotected sex with many partners at an early age is the norm and they encourage others to do it (and attempt to humiliate those that don’t). We need mechanisms to support those that want to resist that pressure: sex education is such a mechanism. Sex education is part of a package of provisions needed to help our teenagers avoid the terrible pitfalls of unwanted pregnancy and venereal disease. This problem is here – pretending that it isn’t won’t make it go away. How else do opponents of sex education propose to deal with the huge problems of STDs and teen pregnancy? Effective and widely supported sex education programs can achieve real results. For example, in the Netherlands, amongst people having intercourse for the first time, 85% used contraception – compared to 50% in the UK.
