The difference is great between the causes of male homosexual behavior and female homosexual behavior. This describes a basic difference. We have 4 genes hooked to our tongue for taste. We create 10 pheromones, one each representing the 10 emotions, and reasonably we may respond to those 10 pheromones with 10 of our 100 olfactory genes. This would allow two possible unusual results.
Habituation takes over in the organism, as receptors begin to store memories.
Androstenone is the sweat and musty or floral smell. Apocrine is the smell of aroused, frightened, or excited. It is produced most abundantly by black males, then caucasian and least by oriental males, with female production less than male production. The human will replace the olfactory neurons, which is nature's way of telling us that these are important, because nature is stingy and not wasteful. Visual neurons and spinal neurons which are destroyed are not replaced.
