Teens offered sex advice
Teenagers in Thailand have been told to use smaller condoms.
The country's Ministry for Public Health has issued the plea because it found that younger boys are buying ill-fitting contraceptive devices to impress their friends.
By doing so, however, they risk spreading STDs, as the condoms will not serve their intended purpose.
Somchaichote Piyawatchwela - the spokesperson for the ministry - said oversized condoms can "slip in action", meaning they fail to do their job.
Thai government figures show an increase in sexually transmitted diseases in recent years among young people.
