Mrs. Sanderson describes Viagra as an aphrodisiac, which is a common misconception. An aphrodisiac is a substance that enhances a person's libido or sex drive. Sildenaphil (Viagra) does not increase libido, therefore it would not be classified as an aphrodisiac, it is classified as a vasodilator. Vasodilators increase blood flow to certain areas of the body by increasing the size of blood vessels, which is how sildenaphil treats erectile dysfunction (ED). It's a myth that it can enhance a sexual experience for men even if they don't have ED, if a man is capable of getting a normal erection on his own, taking sildenaphil will have absolutely no clinical effect.
