Anecdotal, but repeating pattern.
My exhusband would eat vegetarian at home. (strict veg, no egg, minor amounts of dairy)
His erections were strong and eager.
Dining out, he would get meat, or eggs, and often cheese.
After about two hours, and well into the next day, his erections were spongier, and needed more encouragement. We were in our 30s and 40s.
My partner now is mid to late 60s. He is an omnivore. When we hang out with me cooking, or he’s on a salad for every meal kick (he loves salads and rarely adds animal products) he says he “feels younger.” And then demonstrates. Even on tour, he’s obviously feisty.
If I can take it slow, he can stay hard for well more than an hour, and refractory time is less, after a day of veggies.
Firmer, and better recovery, even with medications that impact erections negatively. No stiffy drugs in use.
I was partially surprised at the scene in GameChangers. (Which I watched back-to-back with Magic Pill) Mainly at the speed at which animal products impacted the circularity system. Think of erections as canaries in the blood’s coal mines.
My ex and I didn’t use coconut or palm oils.
My partner doesn’t eat them, but does eat butter.
I’m curious what plant based saturated fats would do on a similar experiment.
