We have chemistry! Lol have any other couples noticed this?

So occasionally, I will use unscented lotions and soaps because, they can be irritating. And I noticed that the times I did this my bf would always say how good I smelled but I didn't use a body spray or anything. And that got me thinking about pheromones and how compatibility isnt only physical or mental but its also very chemical. Like how, your mans "stink" may not be necessarily stinky for you but actually comforting and vice versa. I just thought it was really intresting. Article excerpt attached. "Whether or not pheromones initially affect sexual attraction, other research has indicated that humans might be using a different set of subtle smell cues to help select our mates. Variation in the major histocompatibility complex (MHC), an important set of immune system genes, imbues each of us with a unique "odorprint," like a fingerprint. "With the exception of identical twins, no two individuals are likely to have the same odorprint," Wysocki says. In nature, the sexual union of unlike MHCs yields offspring with more diverse and thus more robust immune systems. Instinct may also guide us in this manner: Previous research has revealed that human females preferred the musk of sweaty T-shirts worn by men with suitably different MHC genes." http://www.scientificamerican.com/article/pheromones-sex-lives/
