The 'fishy' smell lingers around the cunt when the females do
not practise proper personal hygiene, to wash it at least twice a
day.
If they are on medication do disrupts the system and produces a
kinda smell in their urine, if girls do not wash after peeing, it
lingers around and causes it to produce those white stuff which are
'fishy' smell.
Females who takes alot of meat do have a kinda odour on them too if
they do not take enough vegetables, fruits and water. I do not
understand why is that so too... 
Generally if the females do take care of their own diet, trim or
shave their pubes and with proper hygiene they do not have those
smell, and aim of cunninglingus can be achieved --- orgasm /
climax!
