Also a member of the perv club, but, if you don't like them smelling like vagina, then there are a bunch of things you could do:
Lemon Juice should work, or lime, orange, grapefruit, or tomato.
Alcohol should work, I recommend cheap bourbon.
Overpowering it with peppermint oil or patchouli or spearmint leaves should work.
However, the best way to stop your finger from smelling like Vagina is.....
... stick it in her ass.
