Tadalafil is a popular drug which relaxes muscles and increases blood flow to specific areas of the body. It is primarily used to treat erectile dysfunction in men as well as symptoms of benign prostatic hypertrophy.
Besides lack of sexual desire, many men suffer from a small size of the penis. This may be due to inappropriate development of the male sex organ or any other reasons. The problem may lead to unsatisfactory sexual pleasure or failure in performance during sexual involvement.
