I have to say that a combination of garlic ginger and cayenne.. And maybe b6 with zinc with magnesium caps. Cures! The problem. Im 64 and thought that it might just be the ways things go as you age. Two years ago I could hardly get an erection now they are harder than I need lol.... Ive also started mild jelking you'll have to google that one.
The prostate and sperm need lots of zinc.. Thats why I take the supplement... I think that the oils in ginger make you want to have sex (gingerols).. But at least you dont need to worry if you have a dysfuntion.. it took about two weeks to come in strongly so be patient.
