I know for a fact this is true. I have several friends who have confirmed the [sad] reality of NO WHERE NEAR as impressive erections as when in our 20's! I've notice at least a 2" reduction in erection size. When I was in my 20's, at times [as erections fluctuate as much as an inch from time to time, in early adolescence, depending on degree of prolonged arousal], my erections MEASURED from between 8.25" to 9.25" on any given day. Now, they're more like 7"! Please don't tell me I'm lying, and please don't tell me to be grateful! I want to know if anything can be done to re-stimulate the human body to "bring back" that youthful vigor...at least to some degree. Several years ago, I was taking a nutritional supplement that contained--among other ingredients--L-arginine, zinc, and terrestris tribulus, and I "got back" my "old self" erections for the dosage period. I just couldn't afford to keep buying the supplements, and I began to wonder about the long-term health detriments [if any]. Can someone give me a serious answer?
The problem is a combination of diet and exercise. The degree of erection as well as the period of time an erection last can be effected greatly by this. It could also be related to health problems you may have, but if you are otherwise healthy I would say exercise and your diet.
