Hmmm....let's see.....
If fish smells fishy it's not fresh. It's already rotting.
A clean woman's snatch should have no odor to a 'slight" musky smell when not on the rag. i.e. bleeding or INFECTED.
It's been shown/proven that a Man's CUM seems to the culprit behind a Healthy & Clean pussy having a Fishy or otherwise UNPLEASANT smell to it.
So, if she's clean & healthy and you haven't laid her for awhile and then you go down on her & find that "Fishy" smell.....................then some other Dude's Cum is FESTERING inside her and you just ATE his Man Seed second hand!!!
