Using one girl and nine boys, one at a time, we lay the couples next to each other in complete anomnity. They were not to communicate in any way apart from 'feeling and smelling' the other person next to them.
As we have discovered, they are swopping pheromones, a hormone we excrete and absorb to determine compatibility in mating. Kissing is the best way to do this but not necessary. We are showing an open kiss without out actually kissing between nine couples.
