Ejaculation

Filed Under Incest 

Ejaculation is the release of semen from the penis. It is
a normal part of the male sexual response cycle. During
sexual intercourse or masturbation, semen collects in
the ejaculatory ducts, which are located where the ends
of the vas deferentia join the seminal vesicles within
the prostate gland.

When excitation reaches its peak, a spinal reflex causes
the rhythmic contractions of the smooth muscles within
the urethra, penis and the prostate gland, and propels
the semen through the urethra out the tip of the penis in
spurts.

Once a man reaches a certain point of sexual arousal, he
can no longer prevent ejaculation. This feeling of having
reached the brink of control once these contractions start
is known as ejaculatory inevitability.

The rhythmic contractions of the prostate, perineal muscles
and shaft of the penis occur initially at 0.8-second intervals,
just as in women, and account for the spurting action of
the semen during ejaculation. The intervals between contractions
become longer and the intensity of the contractions tapers
off after the first three or four contractions.

The semen does not actually appear until a few seconds after
the point of ejaculatory inevitability because of the
distance the seminal fluid has to travel through the urethra.
During ejaculation, the internal sphincter of the urinary
bladder is tightly sealed to make sure that the seminal
fluid travels forward and to prevent any urine from mixing
with the semen.

Male Ejaculation and Orgasm
Male ejactulation and orgasm are not one and the same process,
although in most men and under most circumstances the two
occur simultaneously. Orgasm refers specifically to
the sudden and rhythmic muscular contractions in the pelvic
region that release accumulated sexual tension and result
in an intensely pleasurable sensation.

Sometimes ejaculation occurs involuntarily and unbeknownst
to the man during sleep. This is known as nocturnal emission
or, in slang terms as a “wet dream” and is particularly
common in adolescents and young men.

Types of Ejaculation
There are several types of ejaculation. In some cases,
the fine-tuned process of this sexual response is disrupted.

Retrograde Ejaculation. In a condition called retrograde
ejaculation, the bladder’s sphincter does not close
off properly during ejaculation, so semen spurts backward
into the bladder. This condition is usually found in some
men who have multiple sclerosis, diabetes, or after some
types of prostate surgery. It can also occasionally occur
in men who do not have any serious problems. It is not physically
harmful, but it does render the man infertile and he may
have a different sensation during ejaculation. A retrograde
ejaculation is also known as a “dry come” because
the man may experience orgasm, but no semen is released
from the penis.
Premature Ejaculation. This condition, also known as
rapid ejaculation, is a sexual response problem in which
a man consistently feels he has little or no control over
the timing of his buildup to ejaculation. Click here for

Retarded Ejaculation. Also known as delayed ejaculation,
this condition is a sexual response problem also known
as ejaculatory incompetence in which a man is unable to
ejaculate even though he is highly sexually aroused.
Female Ejaculation. This has sparked controversy among
sexuality researchers. There is a body of research documenting
that some women expel a fluid from the urethra at the time
of orgasm through G-spot stimulation. It has been theorized
that this fluid may come from a “female prostate, “
rudimentary glands surrounding the urethra whose tissue
corresponds to the male prostate gland. In fact, some suggest
that the female prostate is the anatomical location of
the G-spot. Not all researchers have been able to duplicate
the female ejaculatory response in their studies, but
among those who have, the composition of the ejaculate
is subject to debate. Some researchers have demonstrated
that the fluid emitted is not urine and does not contain
any significant amount of urine. Others assert that the
fluid is urine. Not all women experience the ejaculation-like
response (estimates vary between 10 percent and 40 percent
as to the number of women who have ever experienced ejaculation),
but for those who do, it is perfectly normal.
