i have several years of diet experimentation, including atkins, raw paleo, raw vegan, vegetarian, real milk diet, etc. etc.
all of these diets i did was to solely improve my sexual performance... i have found a diet of meat, vegetables, fruit to be optimal for my performance, eliminating all dairy, nuts, seeds, grains, etc.
as long as i stick to that im well, i have not noticed any difference between doing high raw diet or high cooked diet.
some supplements that i have found useful in maintaining vitality.
msm, borage oil, maca, zinc, magnesium
