By Andrew Irwin-Smiler, Ph. Jim came to me for therapy because he was having a hard time getting it up during sex. I asked him what he thought was causing the problem, and he said it was porn. He told me that he'd been cruising online porn sites for about a year, since his last relationship ended. Jim didn't think he was looking at that much porn, but he couldn't figure out what else it might be.
At the same time, something else is stimulated: your imagination. The nervous system is divided into two parts: 1. If you're not having success Motion erections 6 weeks, consult a professional. Studies are currently underway to see if stimulating this region can help provide a cure for premature ejaculation. Arteries carry oxygen-rich blood from the heart to the organs, muscles and tissues, and veins carry the blood back to the heart, Hot chick with huge boob from Motion erections, back to the lungs to resupply it with oxygen. Advanced sleep phase disorder Delayed sleep phase disorder Irregular sleep—wake rhythm Jet lag Nonhour sleep—wake disorder Shift work sleep disorder. Another possibility is that you need to see an individual therapist to work through some issues regarding sexuality. This climactic finish stimulates the SNS, resulting in constriction of the arteries and allowing the Motion erections that had been trapped to flow back through the veins. Both of these factors can help you pop a boner. It might be easier to conceptualise it as the plumbing system of the body — the heart is essentially a pump, which needs to function efficiently in order to Motion erections appropriate blood pressure.

- An erection clinically: penile erection or penile tumescence is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged.
If you fill it with water, it becomes firm and gains structure as the walls stretch and widen out. Here the similarities end. A penis will not burst or float away, and it is rarely a welcome addition to a party. A penis, contrary to popular belief, is not a muscle, although it does contain a unique muscular structure which plays a key role in the process leading to an erection.
In this chapter we will examine the anatomy and physiology of an erection in detail and why, when it comes to getting hard, it pays to be relaxed. The muscular tissue in the penis is truly unique, specialised to fill with blood in response to an involuntary pathway, essentially an unconscious action like a reflex.
This can be activated by:. Erections happen as a result of relaxation of the arteries and the spongy, muscular tissue in the penis. As these open up, the penis fills with blood which gets trapped there, and it thereby becomes hard.
Compare this to the muscles we can use at will, such as flexing a bicep or giving someone the finger when they cut you up in traffic.
When this process is triggered, a signalling molecule called cGMP is synthesised. It is this molecule which signals to the muscular tissue in the penis to relax and fill with blood, and an erection — whether you wanted one or not — to materialise.
An enzyme called PDE5 is normally around to break it down and, as a result, your erection subsides. These medications are known as PDE5 inhibitors. Like a good three-piece band, all players need to be working well and in unity. A drunk drummer or absent bassist can spoil the show. Or, in this context, your bedroom performance may be below your usual standards, or your erection may not turn up at all.
For healthy erectile function all three of these systems — nervous, cardiovascular and the penis itself — must be working effectively and in glorious unity. Three main systems in the body need to coordinate for an erection to happen It also processes and coordinates erotic stimuli: the touch of a hand, the sweet words of your lover, a complex fantasy involving a nun and a fireman, and the involuntary process which leads to erection.
The nervous system communicates via electrochemical signals which are carried along specialised cells called neurons. These are relatively quick in comparison to other signalling systems within the body such as hormones - this is why an erection can arrive rapidly should something adequately float your boat. The PNS refers to all of the nerves outside of the brain and spinal cord, penetrating internal organs, skin and muscles. It relays information such as touch, balance and temperature to the central nervous system, where it is then processed and made conscious.
The PNS is divided into the somatic and autonomic nervous systems; the latter is highly involved in how your erection functions. Heart rate and digestion, and reflex actions such as sneezing, coughing and vomiting, are all processes which require no conscious control.
These all rely on the autonomic nervous system ANS , which also happens to be the neurological manager of erections. These stimulate complementary sets of reactions within the body. When the body is under stress or senses danger, the SNS is activated. Heart rate is increased, airways within the lungs are dilated, sweat is secreted, the pupil of the eye dilates to enhance distant vision , blood supply to the muscles is increased and less blood is supplied to all organs not necessary to your immediate survival — including the penis.
The result? Less blood is supplied to organs not necessary for your immediate survival — that includes your penis. Sex, unfortunately, is not one such action. This was evolutionarily beneficial when our day-to-day existence largely involved running from predators but as modern human beings, these responses can be unwelcome and triggered at inopportune moments. Your first-night nerves are wrongly interpreted as being chased by a hungry alligator.
And nobody needs an erection with a kilo reptile bearing down on them. Your erection slowly peters away. In men, activation of the PSNS stimulates the arteries and muscular structures in the penis to dilate open , encouraging blood to flow into it and preventing blood from leaving, which causes your penis to become hard. In women, there is similar dilatation of arteries in the clitoris, causing relatively subtler engorgement and enhancing sensitivity.
In contrast, stimulation of the SNS reduces blood supply to the penis and inhibits the erectile response.
Or to bring it to its climatic ending: ejaculation. Depending on how stressed the mind and body is feeling, sexual arousal can be promoted or blocked by autonomic nervous system ANS. But what about the things you are aware of, or that you can control? Sensations of touch and taste, and the voluntary movement of muscles are the responsibility of the somatic nervous system, the other division of the PNS.
Enclosed within the skull and spine are the brain and spinal cord, respectively. These make up the CNS; the system which coordinates and processes every touch, sensation and stimulus received by the peripheral nervous system, and transforms it into conscious perception.
Signals are sent, via the spinal cord, to activate the autonomic pathways with the end result, an erection. The cardiovascular system is composed of the heart and all of the veins and arteries in the body.
Its function is to circulate substances necessary to sustain life, including oxygen and carbon dioxide, sugar, electrolytes, cells which fight infection and hormones. It might be easier to conceptualise it as the plumbing system of the body — the heart is essentially a pump, which needs to function efficiently in order to ensure appropriate blood pressure. The pipes of the body are the arteries and veins, which should be smooth, unobstructed and straight as possible in order to allow uninterrupted, streamlined blood flow.
Arteries carry oxygen-rich blood from the heart to the organs, muscles and tissues, and veins carry the blood back to the heart, and from there, back to the lungs to resupply it with oxygen.
When activated, the PSNS triggers dilatation of arteries in the penis, allowing blood to flow in. But when prompted, provided the heart is pumping efficiently, the arteries are healthy and the nervous system is operating smoothly, it is ready to spring into action like a highly-caffeinated doctor on-call. If the timing and place is right in bed with your consenting partner, right, on a bus, not so right , sex or masturbation may swiftly ensue, followed by ejaculation.
This climactic finish stimulates the SNS, resulting in constriction of the arteries and allowing the blood that had been trapped to flow back through the veins. The penis once again becomes flaccid. There is smooth muscular tissue within the walls of arteries which allow them to widen and narrow. The spongy tissue of the corpus cavernosum of the penis responds similarly.
When triggered by the PSNS, molecular signals result in the relaxation of the walls of the arteries and the corpus cavernosum, encouraging blood flow into the penis, and an erection to proudly present itself. During this process, cells which line the arteries and muscles release nitric oxide, which starts a cascade of signals within the muscle cells. Stopping, or inhibiting, this enzyme before it gets to work, keeps the cGMP intact, the smooth muscles relaxed, and your erection very much there.
They block the breakdown of cGMP, so that blood remains trapped in your penis, and your erection is maintained for the task at hand, be that making slow, passionate love or a five-and-a-half-minute session on a Tuesday night.
The endocrine system consists of a network of organs which regulate the release of hormones into the bloodstream. One of these hormones has become synonymous with all things male, hairy and aggressive: testosterone. Largely produced in the testicles — and contrary to its often bad press — it promotes healthy sperm production, libido, bone and muscle strength.
A number of different theories have been suggested as to how testosterone is involved in healthy erectile function. Some of the suggested roles include:. As research into the roles of testosterone in erectile function grows, new treatment strategies may emerge. But until that time, PDE5 inhibitors remain the prime means to treat the symptoms of erectile dysfunction — and effectively at that. Exactly what this role is remains somewhat of a mystery.

Cardiovascular system 3. Structures within the penis itself. The nervous system is divided into two parts: 1. Central — The brain and the spinal cord 2. Peripheral — The nerves which carry information to and from the brain and spinal cord. When an erection arrives without you necessarily wanting one, you have the peripheral nervous system PNS to thank.
When it struggles to arrive at all, the finger points to its sympathetic subsystem The sympathetic nervous system: stopping erections in their tracks since, well, forever When the body is under stress or senses danger, the SNS is activated.
The parasympathetic nervous system: the hero behind every welcome erection. The somatic nervous system: the bit you can control But what about the things you are aware of, or that you can control? The central nervous system: the mainframe Enclosed within the skull and spine are the brain and spinal cord, respectively.

Now you know how an erection works. The endocrine system where testosterone comes into play The endocrine system consists of a network of organs which regulate the release of hormones into the bloodstream.
Some of the suggested roles include: — involvement in healthy growth and functioning of the nerves involved in erection — involvement in production of nitric oxide, and thus the activity of PDE5 As research into the roles of testosterone in erectile function grows, new treatment strategies may emerge. So now you know: an erection is a truly remarkable piece of physiological engineering.

How Therapy Can Help Men With Porn-Induced Erectile Dysfunction | HuffPost Life
YOU use it every day, and may even call it your pride and joy, but how much do you really know about your penis? You might think you wake up with an erection because you've had a rather erotic dream, but the real reason is far less sexy. Whatever you call it, schlong, willy or todger, your member performs some rather impressive tasks.
In fact, the evolution of the human race has depended on a man's ability to get an erection - so we can safely say your dad's worked. But that being said, your manhood is also capable of letting you down no pun intended and is also slightly uncontrollable. You can actually break your penis - think shattered urethras and torn muscles - enough to make the burliest man wince. From the moment you are born to the time you take your last breath, here are nine things you may not have known about your penis.
That's because having a full bladder stimulates nerves in a similar region to the nerves involved in getting it up, and an erection inhibits your ability to wee. But the same thing can happens when women have a full bladder - their clitoral nerves are stimulated - so it may not be as simple as that. Sleep erections can actually be a useful diagnostic tool for erectile dysfunction. If a man can get an erection when he is asleep but not when he is awake then it is a fairly clear indication that the issue is a psychological one and not physical.
There have been studies to suggest that thinking about something else can delay the grand finale, but the part of your body that controls your orgasm is actually in your spine. Studies are currently underway to see if stimulating this region can help provide a cure for premature ejaculation.
A study published in BJU International found that there is no correlation between foot size and penis length. Another study, published in the International Journal of Impotence Research, found "penile dimensions are significantly correlated with age, height, and index finger length".
You may have thought this ability is something that develops when you have hit puberty but the fact is many penises are born ready. And even before birth some ultrasounds have picked up a fully formed erection, according to Medical News Today.
Here's something that might cheer a lot of men up about death - sometimes you can get it up one final time even once you've passed on. Scientists believe it's caused by pressure on the part of the brain responsible for erections. It often happens during very passionate sex and occurs when the covering of the erectile muscles ruptures - a word no man has ever wanted to hear while getting frisky.
There are several dangerous positions to put your manhood in, think doggy style and cowgirl, and it's painful enough to put a halt on all proceedings for some time. Although, hats off to this guy who fractured his penis during a passionate romp with his girlfriend only to keep going and notice 12 hours later. Studies have suggested that the angle your member dangles at determines the way it points when it stands to attention.
You've heard the saying "show-er or a grower" before, but it actually holds very little value. Some men do grow to be a bigger size when they are turned on lucky them but it's perfectly normal if yours remains the same length.
But don't worry if you're a little on the small side boys, there is no suggestion well endowed men are any better in the sack. We pay for your stories!
