1 5 It is important about Masturbation

post by ableh

Experts say most men have to masturbate, either to reduce stress, help you sleep soundly, and so forth.


Even so, there are medical matters which may never have known about masturbation. These are five important things about masturbation is to know the men:


1. There was no term "masturbation abnormal"

Men often ask if there is something abnormal about the way they masturbate. The experts themselves are reluctant to define the word "normal" or "abnormal", but they claim that men do it with frequency and techniques vary widely.


"As humans, we are too diverse to adopt a particular norm of masturbation is normal or not," said Betty Dodson, PhD, sexologists from New York as well as author of the book Sex for One.


"Every man to masturbate in his own way. Did he use his hands, rubbing on something, using sex toys or household objects, wearing special clothing, fantasizing, seeing a book or magazine, try a different position, or look in the mirror," said Martha Cornog, author of The Big Book of Masturbation.


2. Masturbation does not completely secure.

Unlike sex with a partner, masturbation does not transmit sexual disease. You also will not experience muscle tension, eye bags caused by fatigue, and feeling awkward often faced when having sex with a partner.


But masturbation was not fully secured. "Masturbation is the safest sexual activity ever existed. But, the laws of physics and biology is not going to stop saying that masturbation is safe just because masturbation is normal," said Cornog.


The average man knows, if their frequency or too strong to masturbate while doing it, and it can irritate the skin of the penis. On the other hand, men do not know that the habit of masturbation with a stomach condition, for example by pressing a pillow or even a carpet on the floor, can injure the urethra. Therefore, urine from the penis are not spending as usual, but with a hard spray so difficult to control.


Barbara Bartlik, MD, psychiatrist and sex therapist in New York, said he saw a man who suffered severe urethral trauma due to masturbating face down so that he could no longer be able to use the toilet standing but had to urinate sitting down.


In particular cases are very rare, masturbate or have sex with your partner can also cause penile fracture. This painful condition occurs because the tear in the tunica albuginea (white tissue surrounding the sponge layer of the penis) due to the erect penis of a hard object or being forced to bend downward. In an emergency, this often ends in a condition required surgery.


3. Own sex change your sex life or vice versa.

For various reasons, when their own sex can benefit. Masturbation can help identify your own sexual response-what feels good for you and what did not, so you will be better able to explain to the couple about the right touch.


It also helps you learn to recognize when the "inevitable" right before the orgasm and helps teach couples how to avoid premature ejaculation.


Perhaps most significantly, masturbation is the mechanism or the best solution for men who are not able to have sex when their partner while on sick or menstruating, or own a sex drive that do not comply with himself.


For some men, "solo sex" can become an obsession so they began to lose the desire to make love with their partner. Feelings of hurt and alienation caused by the couple's obsession with "solo sex" will make you difficult to maintain relationships.


The experts stressed, masturbation is fine even for men who already committed. "We can not assume that just because a man masturbating, then it will reap the problems of the primary relationship," said Bartlik.


4. Some triggers masturbation techniques sexual dysfunction.

The experts warn, the man who often stimulate him in ways that do not simulate sex with a partner (eg, stroking very fast or with heavy pressure or friction) may be suffering from ejaculation disorder. With sexual dysfunction is, someone will be difficult or even impossible to reach climax during sex with a partner.


"Anyone who has experienced sexual dysfunction should ask himself whether he had masturbated in a manner which has caused a sensation different from that obtained from the hands, mouth, or vagina partner. Then he must consider what it can stimulate your partner and change the way masturbation you to make such a desirable partner, "said Michael A Perelman, PhD, professor of psychiatry and urology from Weill Cornell Medical College in New York.


5. Masturbation affects prostate cancer risk

A study conducted in Australia in 2003 and published in BJU International states, ejaculation associated with decreased risk of prostate cancer later in life.


However, in a 2004 study published in The Journal of the American Medical Association, a researcher reported that "ejaculation frequency is not associated with an increased risk of prostate cancer." In both these studies, the frequency of ejaculation include sexual intercourse with a partner and masturbation.


Meanwhile, in a study published last January in BJU International showed that young men who masturbate frequently higher risk of prostate cancer. However, if older men often masturbate, it will reduce the risk of prostate cancer. As for having sex with a partner does not become a factor against the risk of prostate cancer.


The researchers assumed that masturbation is not the only one that can trigger prostate cancer risk in men who masturbate often in their 20s and 30s. Men often to masturbate because it has high levels of sex hormones. Young men who are genetically inclined to have hormone-sensitive at high risk of prostate cancer when their sex hormone excess.


Meanwhile, men aged over 50 years of age and often masturbated turned out to help dry the prostatic fluid that may contain substances that trigger cancer.

2 Male Reproductive System


Sperm (male gene carrier) was made in the testes and stored in the seminal vesicle.
When sexual intercourse, the sperm contained in a fluid called semen out through the vas deferens and penis erection.


DEFINITIONS

Outer structure of the male reproductive system consists of the penis, scrotum (sac balls) and testes (testicles).
Inside the structure consists of the vas deferens, urethra, prostate gland and seminal vesicles.

STRUCTURE

The penis consists of
- Roots (attached to the abdomen didnding)
- Body (middle part of the penis)
- Glans penis (tip of the penis is shaped like a cone).
Hole urethra (the channel where semen and urine exit) there is at umung glans penis.
Basic glans penis called the corona.
In men who are not circumcised (circumcision), leather front (preputium) extending from the corona to cover the glans penis.


Agency penis consists of three cylindrical cavities (sinuses) of erectile tissue:
- Two larger cavity is called the corpus cavernous, located adjacent
- The third cavity is called the corpus spongiosum, surrounds the urethra.
If the cavity is filled with blood, the penis becomes larger, stiff and erect (an erection).

The scrotum is a thin-skinned sac that surrounds and protects the testes.
The scrotum also acts as a temperature control system for the testes, because that is normally formed sperm, the testes should have a slightly lower temperature than body temperature.
Kremaster on scrotal wall muscles will loosen or tighten further testicles hanging from the body (and the temperature became colder) or more close to the body (and the temperature becomes warmer).

Testes oval to the size of an olive and is located in the scrotum. Usually the left testis was slightly lower than the right testis.
The testes have two functions, which produce sperm and make testosterone (the primary male sex hormone).

The epididymis is located on the testes and is a six-meter long canal.
The epididymis collects sperm from the testes and to provide space and environment for sperm maturation process.

Vas deferens is a channel that brings the sperm from the epididymis.
This channel runs into the back of the prostate and into the urethra and ejaculatory ducts forming.
Other structures (eg blood vessels and nerves) work together to form the vas deferens and spermatic cord.

FUNCTION

During sexual intercourse, the penis becomes stiff and upright thus allowing the occurrence of penetration (entry of the penis into the vagina)
Erection occurs due to the complicated interaction of the nervous system, blood vessels, hormones and psyche.
Pleasant stimuli cause a reaction in the brain, which then sends signals through the spinal cord to the penis.
Arteries that carry blood to the corpus cavernosal and corpus spongiosum to respond, which is dilated (widened). Widen an artery that causes increased blood flow to erectile area, that area is filled with blood and erectile widened.
The muscles around the veins that normally drain blood from the penis, will slow the flow of blood.
Raised blood pressure in the penis causes the penis length and diameter increases.

Ejaculation occurs when reaching the climax, when the friction on the glans penis and other stimuli transmit signals to the brain and spinal cord.
Stimulate nerve muscle contraction along the lines of the epididymis and vas deferens, seminal vesicles and prostate. These contractions push the cement into the urethra.
Furthermore, muscle contraction around urretra will push the cement out of the penis.
Also constrict the bladder neck so that the cement does not flow back into the bladder.

After ejaculation (or after the stimulus stops), tighten the arteries and veins to relax.
As a result the flow of blood into the arteries and reduced blood flow out of the veins increases, so the penis becomes soft.
