Premature ejaculation occurs when a man ejaculates too quickly and without control. It occurs before or shortly after penetration.
When premature ejaculation happens frequently, it interferes with the sexual pleasure of both the man and his partner. It can become a medical problem due to feelings of guilt, embarrassment, frustration, depression, and will cause stress in even the healthiest relationship.
_ _ _ _ _ _ _ _ _ _ _ _ _ _ The Cause of Severe Premature Ejaculation.
1. _ Extreme levels of arousal caused by the overproduction of sex hormones.
Simply stated - Hormones control "everything" that happens during a sexual performance - from the erection to the ejaculation!
A normal ejaculation occurs when sexual excitement triggers glands, located inside your body, to begin a slow release of chemicals (hormones) into your blood stream. The slow release of these hormones tells your brain to gently stimulate the nerves at the glans (head of your penis). As you become more and more sexually excited, your body produces more and more of these hormones. The sensitivity becomes greater and greater until you reach the point at which time you ejaculate. Under normal circumstances the production of hormone is gradual and a man has the ability to control the sensations of sex.
Premature Ejaculation occurs when your body produces too much hormone too fast. Your body becomes "over stimulated". The head of the penis becomes so sensitive that you ejaculate almost immediately. There is absolutely no control.
This Extreme Sensitivity on the head of your penis causes the ejaculatory mechanism, inside your body, to go into "spasms". It's these spasms that cause the overpowering Urge to Ejaculate.
The head of your penis becomes so sensitive and the urge is so strong that you ejaculate immediately.
If you slow down the production of excess hormone - you slow down the ejaculation.
