To add to the above: ^^^ What I use/consume, and the effects.....
First a little background: 10 yrs ago I was in a long-faded marriage - I'd given up on myself, piled on weight, etc, etc... I was a physical mess.
No sex during the last 4 yrs, I had no interest - Even if I'd wanted to, erections were 'rubbery' and didn't last long enough anyway.
Then I had a blood-pressure scare (stupidly high numbers)
My Doc laid it on the line, and it really sh*t me up! Caused me to re-think life in general... so...
I moved out and got divorced, sorted my diet, dropped from about 295lbs to around 180lbs over the next year or so...
These days, I'm the healthiest I've been since my 30s
• I avoid refined sugars - The lag effect from that stuff is terrible.
• Vit-C with zinc - Multi-minerals that include Boron - Omega-3 fish oil capsule
• Most days I'll drink a glass of pomegranate juice, or a sugar-free fizzy drink that contains L-Arginine (I'm halfway through one right now).
• Every weekend I juice a watermelon (including the pips and rind), add some lime or lemon juice (because watermelon alone is a bland taste), enough for a small glass each morning for the week.
• I've now come off most of the B-P medication, but I continue with the Calcium-channel inhibitor (Amlodipine) because it works by opening blood vessels (The same thing that blue V-Pills do, but a less dramatic effect) - As a by-product.... CC-inhibitors are also a good defence against getting seriously ill from the Covid-bug.
• Occasional VERY dark chocolate.... If I think sex is on the cards that night.
Results...
The hardest boners I've had since my 30s - Morning wood is back with a vengeance (it had stopped during my late 40s)
And when I get down to business, I no longer need any 'downtime' between rounds - So long as there's a willing woman around... once it's 'up', it stays up until I choose to stop (or go to sleep)
Much to the surprise.... and pleasure.... of women who are usually at least 10 yrs younger - One woman of 29 (when I was 54) actually thought I'd popped a 'V' pill (I hadn't)
* I've highlighted what I think are the most relevant things.
Just my own personal experience.... and what seems to work for me.
