Pheromone signals are detected through an organ 3 inches inside the nose called the Vomeronasal Organ (VNO). When the VNO detects the pheromone, it sends a response signal to the brain. So, while the sense of smell is usually discussed in studies of pheromone attraction, it is really a chemical response that occurs, rather than a specific identifiable smell. In other words, she responds to your chemistry on a subconscious level, with feelings of attraction, arousal, interest, and excitement.
Nexus Pheromones are chemical scent signals that all humans/mammals give off. Subconsciously detected, pheromones give information about your immune system, your fertility, your current state of sexual interest… and the list goes on. Some of these pheromones target the opposite sex and naturally trigger attraction arousal and readiness for sex. With the right chemical-hormonal signals, she automatically, instinctively responds — without even realizing what is drawing her to you!
