Your diet definitely affects how your dick works.
Check out Mark Sisson. Listen to what he has to say on the Joe Rogan Podcast (YouTube). He is 63 years old. Shredded. And looks like he stuffs his wife daily and has never heard of ED. His style of eating is called ‘primal’. I think his advice is really great.
There is also a great book called ‘the hardness factory’s where a doc talks about how to eat and live in order to have maximum dick hardness, which also is how to have maximum heart and body health. It’s funny men won’t stop eating cheeseburgers and smoking if you tell them that they will die from it. But they will stop right away if you even mention that their dick won’t work so well.
