Maca Root is a substance known to give stamina and energy. It can also help quite a bit with the sexual act. Sometimes it is simply just helps somebody to have more desire for sex. Because one of the most common things I am finding in my practice these days is that people although they may be ale to go through the sexual act, almost have lost all their desire or libido. So you need to have that component, or it is just not going to be an enjoyable act.
