Hi Melissa, I'm a 67 yr old male and married 46 yrs to my very attractive wife. She has the figure of a woman much younger...gets me turned on. Unfortunately, I have experienced erectile disfunction for several years. I have successfully used an Erectaid, but it is uncomfortable. Additionally, it is a nuisance to have to break into foreplay to use the thing. Most recently I have been perscribed with v1agra with limited success and more recently, Levitra, which I prefer. Most recently I have become aware of Maca. I wondered what experience your clients may have had with this herb. I'm tempted to try it to enhance my libido, which is off. Do you think this or any other compound would enhance my sex drive? Thanks
