Male enhancement may have started with the onset of Viagra. Viagra is actually a treatment for erectile dysfunction, but a number of men have used it as a way of enhancing sexual intimacy. The enormous success of Viagra was followed by the release of nonprescription enhancement products that were specifically designed to meet certain intimacy functions: longer stamina, increased orgasm, size increase, and other functions. The popularity of these nonprescription enhancers has been significant, as millions of men around the world have used one form or another of a nonprescription enhancer. The enhancers work in different ways according to the type of enhancement being performed. A common effect of enhancers is increased blood circulation to the penis. Enhancers come in different forms, including enhancers that are ingested, and topical treatments. Male herbal enhancers are available as well, and typically come in capsule form. Nonprescription enhancers are most frequently sold through mail order, with many orders placed online.
