PRINTED underwear telling youngsters to think twice before having unprotected sex is one of the latest tools to be used to promote good sexual health.

High school students across Lancashire took part in a competition to promote sexual heath and the finalists pitched their ideas to sexual health bosses in a Dragons’ Den-style competition called Lizards’ Lounge.

The youngsters had to explain why their ideas were worth Lizards’ cash – up to £4,000 per project.

Shauna Parker from Southlands School, Chorley, scooped a prize for her monogrammed underwear carrying warnings to make young people think twice.
