Negative attitudes about young people and sex need to stop if we want to improve their sexual health and relationships, a charity chief has said.
The number of cases of chlamydia increased by 252 per cent between 1995 and 2006, according to the sexual health charity Brook, while rates of gonorrhoea increased by 80 per cent.
Syphilis also increased by a massive 1,861 per cent, although the overall number of people with the infection is still much lower than those for chlamydia and gonorrhoea.
Simon Blake, the charity's chief executive, said: "Statements such as 'Shag' - which stands for Syphilis, Herpes, Anal warts and Gonorrhoea' - will not help improve our negative culture."
Mr Blake revealed part of the increase in STI figures is due to more people getting tested and that teenage pregnancy rates are actually the lowest they have been for 20 years.
He concluded that the focus should be "on empowering young people with the knowledge and skills to make their own choices and be responsible".
