all girls are different.. some may smell, others may not, its part of the body. usually if the girl tends to keep it clean and wash often it shouldnt smell bad, but at the same time if there is an infection or something then it might smell
It shouldn't smell... maybe the girl you were with didn't wash well or has some kind of infection. Not every girl smells, though. :)
its when the male sperm is inside the vagina and creates a fishy smell
