I\'ve often noticed a flushing response when wearing pheros (either PF, attraction or edge). I\'ve seen it with males, females, young, old, you name it. It happens very frequently. I don\'t believe that it\'s necessarily a sexual response. In fact, flushing happens frequently from embarrasment or just being flustered and is a vasomotor response. People who have the most severe flushing response also act very serious with me more often than not. Anyone else observe this? With which pheromones?
