what are good vitamins to increase blood flow to the penis?
I am looking for vitamins that I can take that will increase blood flow to my penis. I heard the more blood flow to the penis, the better you perform (last longer) in bed.
I did some research of my own on Google and found on a few websites where people said vitamins E, B1 (thiamine), B3 (niacin), and B12 are good vitamins to take to increase blood flow, but you have to take all of them.
Any information will do. Thank you.
