It apparently contains a section called "an orgasm a day" encouraging educators to inform teens about the positive physical and emotional effects of sex and masturbation, apart from demonstrations about how to use condoms and other contraceptives.
Teachers will now need to emphasise that sexual relations can be healthy and pleasurable instead of simply explaining the mechanics of sex and warning about diseases.
However, some people claim it will increase promiscuity.
"Some of it is good sense, but I think it's wrong is to suggest that 16-year-olds should wantonly enter into having sexual intercourse for pleasure," the Daily Telegraph quoted Anthony Seldon, headmaster of Wellington College, as saying.
He said: "I think this is medically wrong and emotionally wrong and will increase teenage pregnancy and impact negatively on the formation of a long-term loving relationship."
However, Steve Slack, who helped produce the leaflet as Director of the Centre for HIV and Sexual Health in Sheffield, said: "Far from promoting teenage sex, it is designed to encourage young people to delay losing their virginity until they are sure they will enjoy the experience."
Also, Ruth Smith, news editor of Children and Young People Now magazine,believes that the booklet will help young people become more comfortable with their sexuality.
He said: "Research shows young people feel pressured to have sex before they're ready," she said.
"This booklet is intended to give them the skills to discuss it. It's not a licence to go out and have sex, it's saying if you do, do it, wait until you're ready and enjoy it. It makes them more confident and more able to say no."
