Medications. There are several different ED medicines that can help produce an erection, such as avanafil (Stendra), sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). These medications work the same way: they relax smooth muscle and allow increased blood flow into the penis. Testosterone replacement and medications injected directly into your penis to help with erection are also common.
Though few things are worse for your erection than a cigarette habit, coffee can actually help you out below the belt. A study by the University of Texas Health Science Center at Houston found that men who consumed the caffeine equivalent of 2-3 cups of coffee per day were less likely to suffer from erectile dysfunction than those who preferred to wake up with caffeine-free beverages.
"It definitely was a blow to my masculinity," Francis told Mic. "It didn't help that my wife at the time would say that I must be gay if I couldn't keep it up for her." Compounding the issue, if an erection doesn't happen during a given sexual encounter, the man can obsess over it, inevitably creating pressure and making it difficult for him to become fully aroused during future encounters.
"When it's persistent and consistent, it's extremely likely to have biological factors" regardless of age, Dr. Irwin Goldstein, director of sexual medicine at Alvarado Hospital in San Diego and the director of San Diego Sexual Medicine, told Mic. But the cause of ED can also be psychological: For instance, if a man can get an erection on his own but not with a partner, then his ED is more likely to be rooted in performance anxiety or a deeper psychological issue.
"On the physical side of things, we most prominently have physical fitness as the No. 1 factor in erection achievement and sustainability," he continues "If a body isn't healthy, it's going to labor to send blood flowing properly and to function in many respects. Much like a car in need of a tune-up, a body which is out of shape or overweight is going to labor to perform functions — like causing an erection."
Stiffy Solution: Again, saying "stop being so stressed out so you can get boners again" is easier said than done — but a lot of people find sexual dysfunction to be a stronger motivator to live a healthier lifestyle than the threat of, say, a heart attack down the road; so there's a chance that this could actually be a good thing in the long run for your boo, if it helps him take his stress seriously. Relaxation techniques like yoga, exercise, meditation, tai chi, and getting adequate sleep can all lessen the impact of stress on your body (and your dong).
Alcohol: A couple of drinks can loosen your inhibitions and help you relax. But alcohol can also impair sexual functioning. Alcohol works on the nervous system by slowing down brain function, breathing, and pulse. Initially, the effect is often psychologically stimulating, since emotions and desires flow more freely. However, while alcohol may boost sexual desire by helping a person to relax, it can decrease performance, especially where erections are concerned. For this reason, it's best for guys to limit their alcohol intake to one to two drinks (or none at all) for optimal sexual function.
In an article on Men’s Health about things that wreck your erection, some examples of threats to an erection are sugar, lack of sleep, sleeping near a newborn baby, and lack of vitamin D. The common theme in the article is that reduced testosterone impacts your erection. Not all scientists agree with that. But there are definitely links between testosterone and erectile problems.
