Let's talk about sex (and STIs).
Young people from Hertfordshire are helping Cel deal with the sticky issues of sexually transmitted infections - with NHS school nurses providing the answers you might want to hear, like can you catch STIs from a toilet seat?
More than a million people worldwide get sexually transmitted infections every day, but how would you know if you were one of them? How would you feel - and what would you do about it?
