OK, it's pre-watershed so it can't be as bad as it was last time (which was still nowhere near as bad as TV3's A Girl's Guide to 21st Century Sex *heaves*. Anna Richardson presents the 5th run, which features the results of a massive nationwide sex survey revealing the sexual landscape - what people doing, who we're doing it with, and how often. The new series informs parents as to what their kids really get up to, including the use of sexting, internet porn and webcams. The Sex Education roadshow visits schools answering questions about sex and providing much needed no-nonsense education on the subject. There are also films about the 'sexually invisible' - from the blind to people with restricted growth. And the series tackles the thorny topic of sexuality and religion. The first show meets 21-year-old David Smith, a paralympic athlete with cerebral palsy, and 24-year-old fiancée Kat Watkins, who suffers from brittle bone disease. The couple describe how - against all the odds - they have managed to achieve a fulfilling sex life.
