Zicoflex While most of us are
sure that we like to
have sex, most of us
also haven't spent
much time thinking
about what happens
physiologically while we
are engaged in the act.
Masters and Johnson
(two groundbreaking
sex therapists) coined
the term "sexual-
response cycle" to
mean the sequence of
events that happens to
the body when a person
becomes sexually
aroused and
participates in sexually
stimulating activities
(intercourse,
masturbation, foreplay,
etc.).
The sexual-response
cycle is divided into four
phases: excitement,
plateau, orgasm and
resolution. There is no
distinct beginning or end
to each phase -- they're
actually all part of a
continuous process of
sexual response.
Keep in mind that this is
a very general outline of
what happens to each
of us as we become
sexually aroused. There
is much variation among
individuals, as well as
between different
sexual events.
Simultaneous
Orgasms
Both men and women
go through all four
phases, except the
timing is different. Men
typically reach orgasm
first during intercourse,
while women may take
up to 15 minutes to get
to the same place. This
makes the likelihood of
simultaneous orgasm
during intercourse a rare
event.
Phase One:
Excitement
This phase usually
begins within 10 to 30
seconds after erotic
stimulation, and can
last anywhere from a
few minutes to many
hours.
Men: The penis
becomes slightly erect.
A man's nipples may
also become erect.
Women: Vaginal
lubrication begins. The
vagina expands and
lengthens. The outer
lips, inner lips, clitoris
and sometimes breasts
begin to swell.
Both: Heart rate, blood
pressure and breathing
are all accelerated.
Phase Two:
Plateau
The changes that
started in the
excitement phase
continue to progress.
Men: The testes are
drawn up into the
scrotum. The penis
becomes fully erect.
Women: The vaginal
lips become puffier. The
tissues of the walls of
the outer third of the
vagina swell with blood,
and the opening to the
vagina narrows. The
clitoris disappears into
its hood. The inner labia
(lips) change color
(although it's a bit hard
to notice). For women
who've never had
children, the lips turn
from pink to bright red.
In women who've had
children, the color turns
from bright red to deep
purple.
Both: Breathing and
pulse rates quicken. A
"sex flush" may appear
on the stomach, chest,
shoulders, neck or face.
Muscles tense in the
thighs, hips, hands and
buttocks, and spasms
may begin.
