A recent British Government advice leaflet for parents has warned them against telling their kids what is 'right or wrong' when it comes to sex.
The guide suggests that parents should use light and informal moments, such as when watching TV, rather than sitting teenagers down for a "big talk".
According to the leaflet, the purpose of this approach is to encourage openness and honesty.
Moreover, the guide suggests that parents could use the lives of celebrities as a way of introducing the topic.
"Discussing your values with your teenagers will help them to form their own. Remember, though, that trying to convince them of what's right and wrong may discourage them from being open," the Telegraph quoted the leaflet as saying.
The leaflet, titled 'Talking to your Teenager About Sex and Relationships' suggests talking openly about sex, without telling them what is right and wrong, makes teenagers feel under less pressure to have sex, and are therefore more willing to wait.
The guide has also listed the different types of contraception available.
It advises parents to go with their child to visit the doctor, as it can be "difficult" for them.
"Why not offer to go with your daughter or encourage them to take a friend to support them. Or, if you have a teenage son, suggest he talks to his girlfriend about it and visits a clinic with her," it added.
However, Simon Calvert, deputy director of the Christian Institute, has condemned the British government's new leaflet.
"The idea that the government is telling families not to pass on their values is outrageous," he said.
"Preserving children's innocence is a worthy goal. We would like to see more of that kind of language rather than this amoral approach where parents are encouraged to present their children with a smorgasbord of sexual activities and leave them to make up their own minds," he added.
Children's Minister Beverley Hughes said: "When it comes to sex and relationships, young people tell us that they would prefer advice and information to come from their mum or dad. Government doesn't bring up children but it does have a role to play in supporting parents and giving them access to advice and information."
