the "nookie" juice behind the ear thing has been done for centuries... pretty much the first kind of perfume designed to entice the opposite gender (and not just mask BO)
So nuzzle! Dig your nose into your lover's hair, her neck, her armpit, her belly betton, and so on. Inhale and let the chemicals hit your brain. Then use your senses.
Each person has a difference in taste(or smell I guess) with pheromones. Some people's pheromones turn a person on, others they HATE. The good thing about pheromone perfume is that it really works for certain people who are attracted to the pheromone they're using. The bad thing is some people may be adversly affected by the pheromone used in the perfume and absolutely find you disgusting. So in reality it doesn't give you a better chance at all.
