Civil servants suggested lowing the legal age of sexual consent to 14 when asked to present ideas for new laws on personal freedoms.
They also put forward the suggestion that reforms to nudity laws should allow men and women to be naked in public without fear of prosecution.
The nudity proposals are still under consideration, but Prime Minister David Cameron immediately rejected any proposals to lower the age of sexual consent.
A Downing Street spokesman told Sky News that the PM found the idea 'repulsive'.
"The Prime Minister finds the idea repulsive and the idea was shot down outright," the spokesman said.
Sixteen has been the age of consent since 1875, despite many calls to lower it because of increased sexual activity among younger teenagers.
