A new survey has found that increasing number of young Britons are having unprotected sex with a new partner. Researchers surveyed 200 British young people as part of a study of 6,026 people aged 15 to 24 across 29 countries between April and May. It found that 61 percent have had sex, 43 percent of which admitted to having had sex with a new partner without using contraception -- compared to 39 percent in 2009, Sky News reported. Reasons given for unprotected sex with a new partner included not liking using contraception, and being drunk and forgetting precautions. Nearly one in five girls and 16percent of boys said they did not receive any kind of sex education at school. Additionally, 16percent of boys and girls said they did not trust their teachers to provide accurate and unbiased information about contraceptive choices. "There are some excellent sexual health education programs in this country. But still some young people say we don't trust teachers completely," said Doortje Braeken from the Adolescents and Young People for the International Planned Parenthood Federation. "Quite a lot of young people are still afraid to go to services. Whether it's true or not, they fear that the services are not confidential. I think that's one of the major issues why young people don't go to services. "They think 'maybe they'll tell my parents'. There's still this fear of shame around it," Braeken added.
