Actually, when I was thinking about why I got bit so much by mosquitos, I originally thought it was because I gave off pheromones which were attractive to them. But my pheromones wouldn’t attract a mosquito, hopefully they would attract John.
pheromone – A chemical secreted by an animal, especially an insect, that influences the behavior or development of others of the same species, often functioning as an attractant of the opposite sex. (dictionary.com)
