A special pack of condoms - which can only be opened by two people using both hands - has been launched to promote the need for consent in sexual relationships.
Argentinian manufacturer Tulipan designed its 'Consent Pack' to open only when four hands simultaneously press special pressure points on the side of the packet.
Joaquin Campins, the general director of the BBDO agency, which cooperated with the condom brand on the special pack, said: "If it's not a yes, it's a no.
"Tulipan has always spoken of safe pleasure but for this campaign we understood that we had to talk about the most important thing in every sexual relationship - pleasure is possible only if you both give your consent first."
The limited edition 'consent pack' will be given away for free in bars and at events in the Argentinian capital city of Buenos Aires.
