Pheromones are just a tool, a part of attraction. There are other factors when it comes to attraction. Its a combination of
Visual, how you look, the way you carry yourself (body language) symmetry
Olfactory, pheromones, the signals that they send about you. Masculinity, virility, the way we make a person feel when we are around them.
Verbal, compatibility, intelligence. personality
Logic based conscious preferences like wealth, style, values and status.
I am sure I left some out but its not just one of those things that causes attraction its a combination of them. One of them on there own may grab someones attention but attraction occurs when you have multiple qualities the other person prefers. Your not going to attract every single women with pheromones. They dont work that way. They are just a tool to convey information and feeling. One part of helping you “stand out”. Like Pheroquirk and noble mentioned you need to work with them.
Well dbot posted a great Aura theory in another post you should read. Pheromones may be connected to how we carry selves as well.
But basically we all leave a chemical vapor trail that leads to us. Just like most of the time you are aware of where light or sound is coming from without much thought people know where those chemical signals are coming from so I would say yes there is a natural detection process that we all possess.
