Penis Pictures, Erection & Flaccid Soft Anatomy Photos |
The penis becomes erect following a series of sexual events.
First, the penile nerves are stimulated, to produce a sensation known as sexual arousal.
No matter what the nature of the sexual stimulus. Whether it is visual, mental or physical the brain coordinates the following series of bodily events:

Nerve impulses transverse the length of the spinal cord on to the penis thru the dorsal nerve. Smooth muscle within the walls of the penile arteries respond by relaxing.

Subsequently, the soft flaccid penile arteries dilate allowing up to eight times more blood to flow into the corpora cavernosum, (two parallel cylinders that transverse the length of the penis).

The cavernosum become engorged with blood expanding and lengthening the penis.
The expanding tissue then exerts a positive pressure compressing the veins that normally empty the blood from the penis, maintaining the blood in the penile tissue.
When penile ejaculation (climax) occurs or when penile arousal is discontinued the penis returns to its non-erect state.[Image side view photo of erect penis anatomy picture] Related Penis Sexual Function From our Forum Board Discussion PostsSometimes it would just happen. When I was sleeping by myself, I would wake up some mornings with a hard penile erection for no reason in the world. Other times I have to be thinking intimately of that woman I desire for an penile erection.
After the average healthy male climaxes, exactly what happens that enables him to be fully erectready and willing to go again after a period of time? Does his body have to produce more male testosterone?
I used to really enjoy having sex with my wife and used to please her 2 or 3 times in a go. now i am lucky to get and keep my erection.
