The science of love give somebody the third degree. Please read!?

I know that science has proven that if YOU smell someone of the opposite sex and they smell good to you (not perfume learned, natural scent/sweat), that means they are probably compatible, genetically. What I don't know is: If YOU think they smell biddable, is that a guarantee that they think you smell good to them too?
Answers:
it's not compatibility your smelling, its a hormone produced by the body. there's no guarantee that detecting this hormone(your nose is essentially a chemical sensor) mechanism you are compatible with the person the hormone is coming from.
