How much is too much??

how much female"moisture" is common during sex?
how much is too much? It's never to much. More is better than smaller amount in this covering.
Every woman is different - some women are so dry they really need artificial lubrication similar to KY jelly to be comfortable, and some women will actually enjoy a "female ejaculation" next to a gush of fluid!
So there is no "common" amount.
There really is no such article as too much... it won't harm you and if your partner is wearing a condom it won't wound him either (in vocabulary of transmission of STDs).
It depends on the hormone smooth of the day...There is really no such piece as too much - but not enough can be annoying.
