Dear donquixote145,

I am not a physician, nor have I examined you or had you under medical supervision. Hence, I can only defer to the ED meds that are available in this country - Viagra, Levitra, Cialis.

You will need to visit with your doctor to get prescriptions and then try the meds one by one. There's daily dosing of Cialis - that may work better for you? Who knows?

If your ED is caused by "known physiological factors," then your doctor should be up on what's ailing you. If you're on diabetes meds, BP meds, cholesterol meds, BPH meds, antidepression meds, then you've got an issue for sure. And among those drugs, there are also several to choose from. Your doc will be able to help you switch.

Impossible to make recommendations in individual cases like these,

Besides the now famous ED pills, there are herbals like "horny Goat Weed" which apparently is not a joke.  There is the caverject, there are vacume devices.  Even penile implants.  Any and all should be udertaken under doctor knowledge & supervision.  ED is or can be a sign of a number of diseases which should be fully investigated before swallowing a pill.
I happen to have nerve damage from a Neurological Disease.  Yes, it can have sexual effects.  There is no "best"...  treatment alturnatives must be tailored to the individual's circumstances.

I suggest you seek out a Urologist or Men's Health Medical Practice.

Best Wishes,

I've been having problems myself along these lines for a couple of years.  I have neurological problems as well as diabetes, and high blood pressure and I'm on medications for all of it.  

Unfortunately, medical science has not resolved my issues.  Here is a little of what I've discovered working with my doctor:

 - Herbal remedies don't work.  They conflict with the medicines I have to take for diabetes and high blood pressure and actually caused my diabetes to spike when I was taking herbal remedies.

  - Viagra works... but I get major headaches that prevent me from doing anything.  It's sort of like being dressed with no place to go.

  - Levitra works... but I get severe nausea that lasts for about 3 days.  Really.  I can barely keep down food.

  - Cialis works.. but I get both the nausea and the headaches.  While neither are as disabling as with the other drugs, they last longer.  So, the headache lasts for about 12 hours and the nausea has lasted up to 9 days.  My doctor doesn't think the daily cialis will be much better.

Your results will probably vary since everyone's body is unique.  But, I'm very disappointed in science.  

Personally, I think the best and most effective way of treating ED is to find and correct whatever is causing the problem in the first place if that's possible.  In my case, it isn't possible since my spinal damage is permanent and so is diabetes.

I still manage to have fun though... it just takes a lot more mental energy, and sometimes I never actually orgasm.  But, I keep trying.

You have some very good responses here.  I post mine only to show that there are many kinds of disability and the only option is find out what works best for you.  In my case I was diagnosed with prostate cancer 12 years ago and had to choose surgery or radiation to save my life.  The good news is that I'm still here and healty; the bad is that I had some permanent damage from the radiation, but never missed a day of work or experienced any pain.  I'm still glad I chose it because it is less invasive and a number of men I know who chose surgery had severe inconvenience, dysfunction, and even recurrences.  I've tried viagra, levitra, cialis, muse and herbal stimulants.  They all help, and I have no side effects, but I can't sustain an erection.  Guess what?  A loving session with an affectionate provider culminating in BBBJ or HJTC (after I've also pleasured her) is still sublime. As several said, "find out what you can do, and then do it!"

But here are my general thoughts.

Overall health = sexual health. So anything that is good for your overall health will likely benefit ED.

The following are not medical recommendations because I am NOT an MD. Run anything I say in this post by competent medical authorities.

Even if a person is not diabetic, he can benefit from eating as though he were and monitoring glycemic load carefully. Even if a person has no autoimmune issues, he can benefit from eating an overall anti-inflammatory diet. Even if a person doesn't have celiac disease; many benefit from a gluten-free diet rich in vegetables. Even if a person doesn't have lung cancer, many benefit from smoking cessation.

And, of course, frequent vigorous aerobic exercise and progressive resistance exercise as well.

These things can all help address the underlying issues of ED; or help prevent those underlying issues for those who do not have ED.

Another thing that can help that is natural is -- believe it or not -- Kegel exercises. They can improve the firmness of erections and more.
