A spray of deodorant is part of the morning routine, but you could be killing your sex appeal along with those bad odors.

New evidence suggests that gay men are more likely to respond to male sex pheromones than they are to female ones. And the top site for pheromone release? You guessed it, those sweat boxes called armpits.  

Pheromones have no smell, but your senses can identify their presence resulting in sexual excitement.

Though most phermones are extrated from animals and put into perfumes, colognes or other products, the sweat released by your underarms is believed to release them as well.

Scientists had already found that males carry a distinct pheromone called androstadienone found in semen and sweat. However, it has been unclear what effect these pheromones had on members of the opposite or same genders. It turns out that pheromones have a major effect depending on the person's sexuality. Research by Wen Zhou and researchers at Chinese Academy of Sciences published in Cell suggests that homosexual men respond to male pheromones, whereby straight men do not. The study implies that gay men innately perceive androstadienone. 

Phermones are not species specific, meaning it is unclear if any animal (including humans) will feel the affect of specific phermones. Either way, it's worth a try when you are on a mission to pick up a guy or for looking for more excitement.
