Chris, female ejaculation can occur when a woman’s G-spot is stimulated. The G-spot
or Grafenburg spot is a small wrinkly zone at the roof of a woman’s vagina. Many
women find stimulation of this area (by a finger, a sex toy such as a wand or vibrator,
or a penis) to be very erotic. Some women may ejaculate without direct stimulation
of their G-spots--simply getting turned on causes them to ejaculate! There are women
who ejaculate without experiencing an orgasm while others may orgasm without ejaculating.
And certainly some will both ejaculate and orgasm at the same time. While the fluid
that is emitted comes from the bladder, it is chemically different from urine. A
woman may experience a very cleaned out sensation after ejaculating--all the tension
inside of her can feel completely released. I’d imagine you’d like to prevent this
because you’d like your bedding to stay dry! Rather than discouraging your partner
from ejaculating, place a thick towel under her or purchase some large disposable
diapers! (She’ll be glad you did.)
