In a human female orgasm, orgasm is preceded by moistening
of the vaginal walls, and an enlargement of the clitoris
due to increased blood flow trapped in the clitoris's
spongy tissue. Some women exhibit a sex flush, a reddening
of the skin over much of the body due to increased blood
flow to the skin. As a woman comes closer to having
an orgasm, the clitoris moves inward under the clitoral
hood, and the labia minora (minor lips) become darker.
As orgasm becomes imminent, the vagina
decreases in size by about 30% and also becomes congested
from engorged soft tissue. The uterus then experiences
muscular contractions. A woman experiences full orgasm
when her uterus, vagina and pelvic muscles undergo a
series of rhythmic contractions. The majority of women
consider these contractions to be very pleasurable.
After the orgasm is over, the clitoris
re-emerges from under the clitoral hood, and returns
to its normal size in less than 10 minutes. Unlike men,
women either do not have a refractory period or have
a very short one and thus can experience a second orgasm
soon after the first; some women can even follow this
with additional consecutive orgasms. This is known as
having multiple orgasms.
After the initial orgasm, subsequent
climaxes may be stronger or more pleasurable as the
stimulation accumulates. Research shows that about 13%
of women experience multiple orgasms; a larger number
may be able to experience this with the proper stimulation
(such as a vibrator) and frame of mind. However, some
women's clitorises are very sensitive after orgasm,
making additional stimulation initially painful.
It is possible to engage in deep,
rapid breaths while continuing stimulation and making
a conscious intention to release the pain and tension.
Doing this can allow for the intense stimulation to
be interpreted not as painful but as intensely pleasurable.
