What is a VNO organ and how does it decide whom you're attracted to and whom you are not?
We all have a vomeronasal organ (VNO) up against the septum inside the nose that is lined with receptor cells drawn to other peoples body scents. This organ is functioning all the time and is responsible for whom we are attracted to.
It all starts at the onset of puberty; the Apocrine glands begin to secrete your own body scent specific to YOU, that can be found on the fands, hands, cheeks, scalp, breast
areolas, and other places hair grows on the body. These scents are called pheromones.
You secrete the scent, and other people pick it up with the VNO organ. They will either be attracted to you or not.
There is a pheromone cologne/perfume that you can wear that doesn't have a perfume scent, it just works to enhance your own natural pheromones to draw others to you.
