The Sex Education Show (4) - S5.E4

A frank look at the world of sex. The roadshow visits Elliott school in Putney, south London, where pupils are taught about the three stages of pregnancy.

The pupils learn the eye-watering truth about pregnancy from their mums. And learn about birth itself on a visit to a labour ward.

Celebrated broadcaster and Rabbi, Lionel Blue, and orthodox Jew, Oli Kasin, reveal their very different experiences of growing up as gay men in the Jewish community.

There is a report on kids and social networking sites.

And more results from the Great British Sex Survey reveal how many people have had anal sex, and in which part of the country is dressing up to explore a sexual fantasy most popular.
