Or, perhaps, since it's been only eight months, it might actually scare you a bit. It can be unsettling when someone falls head over heels. It can be hard to trust that kind of enthusiasm, especially if you've been burned by someone who went from hot-and-heavy to suddenly cold. Even if you're crazy about him, you might need to slow things down a little. Or maybe it's harder for you to say than it is for him — and that's why it rubs you wrong.
However, a review of a United Kingdom medical record database found no evidence that the use of 5-alpha reductase inhibitors independently increase the risk for ED. In 71,849 men with benign prostatic hyperplasia (BPH), the risk of ED was not increased with the use of finasteride or dutasteride only (odds ratio [OR] 0.94), or a 5-alpha reductase inhibitor plus an alpha blocker (OR 0.92) compared with an alpha blocker only. In addition, the risk of ED was not increase in 12 346 men prescribed finasteride 1 mg for alopecia, compared with unexposed men with alopecia (OR 0.95). The risk of ED did increase with longer duration of BPH, regardless of drug exposure. 
Causes contributing to erectile dysfunction can be broadly classified into two categories: organic and psychologic. In reality, while the majority of patients with erectile dysfunction are thought to demonstrate an organic component, psychological aspects of self-confidence, anxiety, and partner communication and conflict are often important contributing factors.
Whenever I am prescribing a medication to a patient, I’m always asking myself, what can the patient do before requiring the medication? What changes do they have to make in order to reduce the amount of medication or preclude their even needing it? So a good candidate is somebody who has an understanding of a healthy lifestyle, about physical activity, about sleep, about nutrition, alcohol, smoking. So patients, individuals, have to do their share before they’re a candidate for anything. All right?
Prevention of some of the causes that contribute to the development of erectile dysfunction can decrease the chances of developing the problem. For example, if a person decreases their chances of developing diabetes, heart disease, and hypertension, they will decrease their chances of developing erectile dysfunction. Other things like stopping smoking, eating a healthy diet (heart healthy with adequate vitamin intake), and exercising daily may reduce a person's risk.
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.
Anxiety is particularly pernicious. It triggers the fight-or-flight reflex that sends blood away from the central body, including the penis, and out to the limbs for self-defense or escape. Less blood in the central body means less blood available for erection. Erection dissatisfaction is upsetting, but try to accept it. It’s normal. And when men become anxious about it, erections become less likely.
A good indicator that "everything is in working order" and that it is probably a psychological cause is if a “morning erection” is still experienced. Feelings like fear, anger, distress and anxiety cause part of the nervous system to come into play which directly blocks the action of another part of the system involved in creating an erection. This is a natural reaction – our ancestors would find it more difficult to run from a predator with an erection in the way!
Because of the difficulty in defining the clinical entity of erectile dysfunction, there have been a variety of entry criteria for patients in therapeutic trials. Similarly, the ability to assess efficacy of therapeutic interventions is impaired by the lack of clear and quantifiable criteria of erectile dysfunction. General considerations for treatment follow:
Studies to further define vasculogenic disorders include pharmacologic duplex grey scale/color ultrasonography, pharmacologic dynamic infusion cavernosometry/ cavernosography, and pharmacologic pelvic/penile angiography. Cavernosometry, duplex ultrasonography, and angiography performed either alone or in conjunction with intracavernous pharmacologic injection of vasodilator agents rely on complete arterial and cavernosal smooth muscle relaxation to evaluate arterial and veno-occlusive function. The clinical effectiveness of these invasive studies is severely limited by several factors, including the lack of normative data, operator dependence, variable interpretation of results, and poor predictability of therapeutic outcomes of arterial and venous surgery. At the present time these studies might best be done in referral centers with specific expertise and interest in investigation of the vascular aspects of erectile dysfunction. Further clinical research is necessary to standardize methodology and interpretation, to obtain control data on normals (as stratified according to age), and to define what constitutes normality in order to assess the value of these tests in their diagnostic accuracy and in their ability to predict treatment outcome in men with erectile dysfunction.
In the meantime, make sure he gets some rest and takes it easy. The more you two stress about it — and the more pressure he feels you are putting on him — the harder it will get for him to get hard, in all likelihood. So take a few days off. Relax, be patient, and help him find him some help if he needs it. In the meantime, here's a Cosmopolitan.com guide about exactly this topic from sex therapist Dr. Jane Greer.
The user should stop using the vacuum pump if pain occurs... Use of a vacuum pump may bruise or rupture the blood vessels either immediately below the surface of the skin or within the deep structures of the penis or scrotum, resulting in hemorrhage and/or the formation of a hematoma. There is now sufficient information available regarding the risks, benefits, and use of vacuum pumps.

Conditions that may be associated with ED include diabetes, [25, 26, 27] hypertension,  , and CAD, as well as neurologic disorders, endocrinopathies, benign prostatic hyperplasia,  , sleep apnea  , COPD,  and depression (see Table 1 below). [32, 33, 34, 35] In fact, almost any disease may affect erectile function by altering the nervous, vascular, or hormonal systems. Various diseases may produce changes in the smooth muscle tissue of the corpora cavernosa or influence the patient’s psychological mood and behavior.
Tadalafil shares the common side effects of the PDE5 inhibitors, however, due to its effect on PDE11, another phosphodiesterase located in muscle, tadalafil has been associated with muscle aches. Back pain and muscle aches occur in less than 7% of men taking tadalafil and in most patients will go away without treatment within 48 hours. When treatment was necessary, acetaminophen (Tylenol) and nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Motrin, Advil) or naproxen (Aleve) were effective. Rarely do the muscle aches and back pain cause men to stop using tadalafil.
None of the ED drugs is safe to take with cardiac drugs called nitrates because it could cause a dangerous drop in blood pressure. Drugs that many men take for urinary symptoms, called alpha blockers, can also lower blood pressure, so take them at least four hours apart from ED drugs. Your doctor may start you on a smaller dose of the ED drug if you already take an alpha blocker, or may recommend the alpha blocker tamsulosin (Flomax), which affects blood pressure less.
This is similar to magnetic resonance imaging. Magnetic resonance angiography uses magnetic fields and radio waves to provide detailed images of the blood vessels. Doctors may inject a "contrast agent" into the patient's bloodstream that causes vascular tissues to stand out against other tissues. The contrast agent provides for enhanced information regarding blood supply and vascular anomalies.
ED is defined as the inability to achieve a full erection or the inability to maintain an erection adequate for sexual intimacy. Other types of sexual dysfunction such as premature ejaculation and low libido may occur; however, the most common and disruptive problem in men is ED. Although most men will experience periodic episodes of ED, these episodes tend to become more frequent with advancing age.
Impotence is the inability to get and keep an erection hard enough to have sex. Many men experience difficulties getting an erection when they are tired or stressed. This is normal and it doesn’t require treatment. However, if you encounter problems that persist, you may be suffering with a degree of impotence. Impotence is a very treatable condition and help is available either when you visit your local GP or an online doctor.
The vacuum device creates a vacuum to pull blood into the penis. Unlike a normal erection, the inflow of blood does not continue once the individual removes the vacuum device. The rubber band placed at the base of the penis constricts the penis to prevent the blood from leaving the penis. As there is no inflow or outflow of blood when the rubber band is in place, it is uncommon for the tip of the penis (the glans) to appear a little blue and the penis to be cooler. Once intercourse is completed, the individual removes the rubber band and the blood drains out of the penis.
The dorsal artery provides for engorgement of the glans during erection, whereas the bulbourethral artery supplies the bulb and the corpus spongiosum. The cavernous artery effects tumescence of the corpus cavernosum and thus is principally responsible for erection. The cavernous artery gives off many helicine arteries, which supply the trabecular erectile tissue and the sinusoids. These helicine arteries are contracted and tortuous in the flaccid state and become dilated and straight during erection. 
It is important that all erectile dysfunction is reported to your doctor, as sometimes it can be an indicator of something physically wrong with you that has to be treated. Also, your doctor is in the best position to find the reason for your erectile dysfunction. Routine questions and tests will provide a guide to the cause and allow your doctor to decide what kind of treatment you might need to deal with it. This may involve referral to a specialist. Detailed information can be found at the website of the Impotence Association – www.sda.uk.net
It's unlikely. Testosterone levels fall as you get older but they have to fall really low to cause erectile problems. Thus assessment for erectile dysfunction includes a testosterone blood test but only replacement if it is very low. Giving someone more testosterone than their body would have made, even at a young age, can cause blood clots due to blood thickening and even reversible infertility. So don't be tempted with homespun remedies.
Erection dissatisfaction can actually enhance lovemaking. The dark cloud of erection changes has a silver lining. Young couples often have problems because young men become aroused faster than young women. Young men are often all finished before young women have even started to get aroused. Post-50 erection changes slow men’s arousal process so their erotic pace more closely matches women’s. A slower pace allows plenty time for kissing, cuddling, and whole-body massage, all essential to most women’s enjoyment of sex. Seen in this light, for many older couples, erection dissatisfaction can be a gift.
Additionally, the physiologic processes involving erections begin at the genetic level. Certain genes become activated at critical times to produce proteins vital to sustaining this pathway. Some researchers have focused on identifying particular genes that place men at risk for ED. At present, these studies are limited to animal models, and little success has been reported to date.  Nevertheless, this research has given rise to many new treatment targets and a better understanding of the entire process.
When we say it’s a barometer of men’s health, it’s a signal. It’s an indicator that things may be right or not. And so when a man develops an erectile problem– and we’re talking about something that is occurring over time. It’s not something that just occurred overnight. When it occurs overnight, it’s more often than not a psychogenic, an anxiety reaction.
