for those who havent gained!
Your penis is not a separate entity from your body. It is part of your body. So if you are in poor health you should not expect your penis to be in any better health than the rest of your body. If you are under great stress, deprived of quality sleep and rest, suffering from an illness or are just malnourished due to a nutritionally deficient diet, you may lack the penis performance that you desire.
