Men are very susceptible to visual stimulation, particularly as children and teenagers. Seeing anything appealing (say, a person or image) activates pathways in the brain that tell nerves in your lower spinal cord to trigger a release of nitric oxide, which relaxes blood vessel walls and floods your penis with blood, making it hard. Nitric oxide is the key chemical here, as you need a mix released from your nerves AND from your blood vessels to get an erection. If the blood vessels, nerves, or both are damaged, it's difficult to get a hard erection. That's why your doctor may well be interested if you're struggling with erections, as it could be a sign of early heart disease or diabetes.
Well, men go through the exact same anxieties, but the difference between men and women is the result is far more obvious in men. The first thing you need to do when you suspect your man is suffering from anxiety-induced erectile dysfunction is to look at him while you're going down on him and say this: "Is there anything you'd really like me to do? I'm willing to do whatever turns you on."
Among the phenomena in the ageing man are a decrease in erectile function and testosterone levels. Add to these, increased risk for CVD, muscle wasting, decrease in bone density and libido, with all of these factors having an interplay with testosterone metabolism.33 Androgens play a key role in maintaining erectile function through four main mechanisms. Androgen deprivation has been shown to result in impairment of NO synthase release, altered PDE5 expression and activity, impaired cavernosal nerve function, and contribution to veno-occlusive disease in the penis.34 The role of testosterone replacement therapy (TRT) as a potential to improve erectile function in the man with ED remains an issue for patient and physicians who are comfortable treating androgen deficiency which include primary care physicians and specialists. Androgens are known to have a significant impact on the function of the smooth musculature within the corpus spongiosum.35

Sexual functioning involves a complex interaction among biologic, sociocultural, and psychological factors, and the complexity of this interaction makes it difficult to ascertain the clinical etiology of sexual dysfunction. Before any diagnosis of sexual dysfunction is made, problems that are explained by a nonsexual mental disorder or other stressors must first be addressed. Thus, in addition to the criteria for erectile disorder, the following must be considered:
Other medical therapies under evaluation include ROCK inhibitors and soluble guanyl cyclase activators. Melanocortin receptor agonists are a new set of medications being developed in the field of erectile dysfunction. Their action is on the nervous system rather than the vascular system. PT-141 is a nasal preparation that appears to be effective alone or in combination with PDE5 inhibitors. The main side effects include flushing and nausea. These drugs are currently not approved for commercial use.
In some cases, nocturnal penile tumescence testing is performed to find out whether the man has erections while asleep. Healthy men usually have about four or five erections throughout the night. The man applies a device to the penis called a Rigiscan before going to bed at night, and the device can determine whether he has had erections. (If a man is able to have normal erections at night, this suggests a psychological cause for his impotence.)
Most bouts of ED can be explained away by stress, anxiety, or nervousness. If erectile dysfunction becomes frequent, don’t panic, but cover your bases by seeing a doctor to rule out scarier causes like diabetes or prostate cancer. Medications like antidepressants can also cause boner loss. Unless you can’t get it up after a date because you spent the day snorting coke and fucking your ex (in which case figure some shit out before you see other people) this line places the blame on the stress of work and away from your partner. While a woman will usually be understanding, she may fear you can’t get hard because you’re not attracted to her. Ease these anxieties with this line. Even if work was great and you’re having trouble getting it up because of other stress, like a text from an ex or family shit you’re not ready to disclose, I’ll allow a little white lie in this instance.
For many men, there is no direct factor involved in erectile dysfunction other than the natural process or aging. As men age, the testosterone hormone decreases in productivity and circulation. Basically, the body is saying that the man has done his job, especially if he has had children. During this time of drawdown on testosterone, men may experience weaker erections, more difficulty in achieving erections, and more difficulty in maintaining erections.
Achieving an erection is a complicated process, requiring transmission of sensations from the genital area to the nervous system and the return of nervous impulses to the muscles and blood vessels of the penis. Anything that interferes with this interchange, such as disease or injury of the blood vessels, muscles, or nerves, can make achieving and maintaining an erection difficult. Psychological factors, such as anxiety and depression, can also interfere with erectile function. Anxiety and depression may also develop as a consequence of impotence.

The association between low testosterone and ED is not entirely clear. Although these 2 processes certainly overlap in some instances, they are distinct entities. Some 2-21% of men have both hypogonadism and ED; however, it is unclear to what degree treating the former will improve erectile function.  About 35-40% of men with low testosterone see an improvement in their erections with testosterone replacement; however, almost 65% of these men see no improvement. 
Chronic stress dumps adrenaline in your system multiple times a day. And that can lead to high blood pressure, heart disease, obesity, and diabetes. Chronic stress is like red-lining your car all day long. When you drive 100 mph all the time, something is going to break down. A high-stress environment can actually change the way your brain sends messages to your body. Dumping too much adrenaline into your bloodstream can affect blood flow and severely limit your ability to achieve and maintain an erection.
In some cases, ED can be a warning sign of more serious disease. One study suggests ED is a strong predictor of heart attack, stroke, and death from cardiovascular disease. The researchers say all men diagnosed with ED should be evaluated for cardiovascular disease. This does not mean every man with ED will develop heart disease, or that every man with heart disease has ED, but patients should be aware of the link.
