More than a quarter of British people do not use contraception when they have sex for the first time, a new survey has revealed.
According to research by condom manufacturer Durex, teenagers are more likely to consider their sexual health than those in their 20s, with nearly 80 per cent of 16 to 19-year-olds using contraception during their first sexual experience.
However, just 50 per cent of people aged between 25 and 34 said that they had used contraception the first time they had sex.
The Family Planning Association revealed that the results were as expected.
"This shows that we should not forget about older age groups when it comes to safe sex messages," a spokeswoman told BBC News.
"It is easy to assume that as they may have been in relationships they know what they are doing, but this is not always the case. We need to have a renewed focus on them," she claimed.
A recent survey by schools watchdog Ofsted found that young people are more likely to turn to magazines for advice on relationships, sexual health and contraception than to talk to their parents or teachers.
