It probably means that you are sucking on the hickey way to hard and you are accidentally pulling blood out from the hickey. If you think that that is gross, you should just either stop giving hickeys or stop sucking on them so hard! that will decrease the taste of blood for sure.

the best place to give a hickey would probably be on the upper body like the neck, chin, cheeks, but this is COMPLEATLY up the person giving the hickey because they may not want one but at the same time it will probably be best to let it come naturally if you know what i mean :) good luck
