This claimed to be the first adult sex education TV series when it was broadcast in the summer of 1977, which it may well have been in light of the 1976 Thames series/programme of a similar ilk "Sex in our time" (aka "Women, Sex and Identity") being pulled *ahem*. Surprisingly next to no info on the YTV series turns up on the internet, apparently it was presented by Gaie Houston. Does it still exist? It's the sort of thing you'd expect to have seen on 70s clip compilation shows on a regular basis. Curiously, Ulster showed the ITV Schools sex ed programme "Living and Growing" in a late night slot in 1978. Channel Four eventually screened an edition of "Sex in our time" during their banned season in 1991.
