TweetIs it? Ive heard there is science that proves that its from hardening of the penis arteries from eating too much crap. Think of that next time you want to go thru the Mcdonalds drive thru window. I believe thats true and I think guys who consume a lot of alcohol will definitely have ED eventually. Ive seen videos of 80 year old health freaks who swear they have no ED and take no Viagra. Well, if I am going to live to be 100, it better not be with ED. lol Thoughts on this?
