Chances are that you have heard of the word aphrodisiac. These are supposed to be drugs, drinks, of food items that are going to stimulate sexual desire. A few options that you have may have heard of before include oysters and Spanish Fly. Even though these are sometimes touted as way to deal with low male libido, there are no scientific studies that highlight the effectiveness of these products.
That does not mean that you will not benefit from taking them (after all, if you have a mental block and BELIEVE you are going to be better in sex, chances are that you might be) but there is no actual evidence that this is going to have any type of effect on you.
Oftentimes these options just mean that you are wasting your money rather than dealing with the causes of low male libido.
