Organize a day with a group of people with three sport activities:
First will be swimming: undressing, seeing each other’s without the clothes barrier although limiting the interaction in the changing rooms.
Secondly, a volleyball match: team up, trust your team and work towards a common goal. Third and last: a dancing class. Pick a person you’ve become closer with in the previous two steps and try Cha Cha Cha. Or even Tango.
