Teenagers are being let down by sex education that doesn't tell them it's best to wait until you're an adult and have one sexual partner for life, a visiting physician says.
But Family Planning disputes United States psychiatrist Dr Miriam Grossman's characterisation of New Zealand's sex education. She has been brought here by the conservative lobby group Family First to speak at a conference in Auckland on Thursday.
Dr Grossman said she took up writing and speaking on the "harms" of sex education after her experiences as a campus psychiatrist at the University of California.
She saw many female students who were panicking about having, or possibly having, a sexually transmitted infection (STI), being pregnant, having had an abortion, or being confused about their emotional attachment to a man who had no intention of becoming emotionally attached to them.
"They didn't understand we are wired, both men and women, but especially women, to become emotionally attached to people we are intimate with."
