I only wish someone had told me this when I was a teenager; I had no idea:

A leaflet promoting the idea that sex is fun sounds like a waste of taxpayers’ money. Uh, tell us something we don’t know.

But a sex education leaflet telling teenagers that sex is fun – in a bid to prevent underage pregnancy and sexually transmitted infections – is not only a waste of taxpayers’ money, it’s misguided do-gooding gone crazy.

And yet that’s exactly what NHS Sheffield has just published.

The leaflet, entitled ‘Pleasure’, advises school kids that they not only have a ‘right’ to an enjoyable sex life, but also that regular sex is good for their health.

Its authors believe it’s time to update the sex education message, which they say has for too long concentrated on contraception and the need to be in a loving relationship, and ignored the main reason people have sex — because it’s jolly good fun.
