A National Health Service leaflet is advising school pupils that they have a “right” to an enjoyable sex life and that regular intercourse can be good for their cardiovascular health.

The advice appears in guidance circulated to parents, teachers and youth workers, and is intended to update sex education by telling pupils about the benefits of sexual pleasure. For too long, say its authors, experts have concentrated on the need for “safe sex” and loving relationships while ignoring the main reason that many people have sex, that is, for enjoyment.

The document, called Pleasure, has been drawn up by NHS Sheffield, although it is also being circulated outside the city.

Alongside the slogan “an orgasm a day keeps the doctor away”, it says: “Health promotion experts advocate five portions of fruit and veg a day and 30 minutes’ physical activity three times a week. What about sex or masturbation twice a week?”

Steve Slack, director of the Centre for HIV and Sexual Health at NHS Sheffield, who is one of the authors, argues that, far from promoting teenage sex, it could encourage young people to delay losing their virginity until they are sure they will enjoy the experience.

Slack believes that as long as teenagers are fully informed about sex and are making their decisions free of peer pressure and as part of a caring relationship, they have as much right as an adult to a good sex life.

Anthony Seldon, master of Wellington College, Berkshire, who introduced classes in emotional wellbeing, said the approach was “deplorable”.
