Why Did She Smell So Good?

This. Pheromones don't exist in humans.

Edit:

So many people here believe in pseudoscience.

But there is no evidence of a consistent and strong behavioral response to any human-produced chemical cue.

A new study throws more cold water on the idea, finding that two pheromones that proponents have long contended affect human attraction to each other have no such impact on the opposite sex—and indeed experts are divided about whether human pheromones even exist.

The unfortunate side of such generalizations <from insects> is the tendency to think of mammalian communication in terms of simple stimulus-response systems. For example, it is now relatively common usage to refer to “aggression-promoting (or “eliciting”) and “aggression-inhibiting” pheromones in mice (e.g., Lee & Griffo 1974; Mugford & Nowell 1972). The obvious implication of this terminology is the existence of two simple urinary compounds which unequivocally either release or inhibit a stereotyped aggressive response. Mammalian social behavior simply does not work that way except at the purely reflexive level. As described in great detail in my book (Doty 2010), attempts to identify mammalian pheromones have been generally unsuccessful, regardless as to whether such agents are viewed as releaser pheromones, priming pheromones, modulating pheromones, or any other type of putative pheromone. Such attempts fall prey to a number of conceptual, operational, and practical problems that go beyond issues of semantics, including assumptions related to innateness, chemical complexity, and the nature of perceptual systems in general.

No study has led to the isolation of true human sex pheromones, though various researchers have investigated the possibility of their existence.

Sorry that you bugmen have to work for attraction instead of hoping girls will fall in love with your stench. Maybe in another life you'll be reincarnated as insects.
