I think we're talking on two tracks here, natural body smell/pheromones, and then the perfumes "secret weapon" sprays etc that are claimed to have pheromones in 'em.
Maybe it's possible to use the right pheromone perfumes etc assuming they work, to help one pass?
In any case, in my own life I've found myself VERY interested in this or that girl once I got close enough to smell her.
