What is this uncontrollable fluid?

no its not pee
(eww)
but even if im not thinking of anything gross or perverted I feel my wetness in my underwear(yes the kind when a female is attracted)

That's normal. The vagina is a self-cleaning organ and that is its way of keeping healthy.
Side thought- it is ok to think sexual thoughts; don't view it as gross or perverted; it is a normal human reaction.

it's actually quite common, you can ask for birth control pills to regulate this fluid.

Yes as every body here is wright. You its normal, unless its a weird color.
