How would tackle the problem of rape?
In the UK, an ad campaign targetting men has begun saying that unless a woman actively says yes to sex, then they must assume that the answer is no.
The campaign will feature adverts on the radio as well as in men's magazines, on condom machines and in men's toilets in pubs.
Do you think this will work?
We will go around the world to see how other countries are tackling the issue of rape and ask whether they think this tactic will work.
We already have started the debate online. to read what others are saying about the initiative in the UK.
