A problem with using Viagra, is not getting to the underlying problems of why a guy may feel or needs to use it. If you ever visit any Erectile Dysfunction Forums, some guys on there will also talk about this. And it's interesting to see how those selling pharmaceutical solutions will heavily troll and attempt to drown out any alternatives. Unnatural pharmaceutical drugs can have unintended and damaging effects, that might not become known until years after the fact.
The point of choosing effective natural remedies or those that would clearly work with how a man's body naturally gets an erection (increasing Nitric Oxide production- like L-Citrullene...), are they can be a part of restoring your health or living healthier.
The other part is the psychological issues, like performance anxiety. As a swinger, I strongly understand and had to confront this issue. A man that can get himself to perform naturally under pressure, can be mentally stronger one than one who needs drugs. And this greater control, can be helpful in how he interacts with women.
Sometimes, it's the interaction between the man and the woman he's having sex with. Some women are way more helpful and skilled, where others make stress or any problems worse. Understanding the issue, can help men choose better female sexual partners or help men on how to guide women on what works best for them sexually; what turns them on or makes them erect.
Now with that typed, some men do have major health or psychological problems that are complicated to fix. Viagra might be the easiest solution in those situations. I'm not saying you can't use it, but it might be worth it to look into alternatives. People should be wary of the pharmaceutical industry's quick fixes, when nature might have a better or almost as good answer, that's more naturally compatible with your body.
I am afraid, my friend, you are falling into the usual misconception that everything "natural" is good. Many "natural" products are actually dangerous, and even more so because they are not submitted to the same regulations that pharma products. Nature produces 1000 times more poisons than human will ever be able to create...Digitalin is a natural product that can kll you in a few minutes if overdosed. Mushrooms produce highly toxic products. Many women who considered themselves "constipated" use "natural" products which destroy their colon (sene for example), all that claiming: "It's natural".. It is but lead them straight to drastic colon removal surgery....
I have been involved with the discovery of viagra, at an age when I did not need it at all.. As you probably all know, it was developed as an hypotensive, and when adm mistered, as all new drugs should, to young healthy volunteers, they all came back smiling...
And also, the usual skepticism about the Pharma industry comes often from those of us lucky enough to be healthy, but is definitively not shared by those who are not not, ask them , cancer patients, HIV, meningitis, gastric ulcers etc..
Having said that, I will repeat that nothing is ever just black or white, yes, of course, the pharma is a business and wants to make money, but I prefer a business making money treating people that those building arms, or even making fast cars in which people can kill themselves..
Back to Viagra: Erectile dysfunction (ED) is a global term which groups several different conditions which require different approaches, and yes, of course, we all know about the fear of failure etc... Nobody denies the brain-sex relationship, (no more, actually than the brain-gut relationship...) Viagra, paradoxically perhaps, can help even the so-called "psychological" ED by providing confidence. And for those with pathologic cause, such as diabetes, atherosclerosis, Viagra is a perfectly fine treatment,
with a perfectibility defined mechanism of action, well studied, with now more than 15 years of experience. None of the "natural" therapies you advise have been studied the way Viagra has been, and nobody knows whether such therapy may not be detrimental on a long run...
To each his own, but my dates should be reassured that I will be able to perform when I meet them, and I don't think they worry whether this is thanks to Viagra, bananas or else...For sure, they will prefer that is is not garlic!!
Just my opinion(s)....
