Though it may seem to be a natural and effortless occurrence, performing sexual intercourse requires any number of physical functions in both men and women to occur. In the absence of these physical functions occurring as they normally do, sexual intercourse can be difficult or even impossible to perform. Though women can and do have difficulty with sexual functioning, whats likely the most commonly occurring sexual dysfunction is a man being unable to achieve erection.

Erection problems arent infrequent, though not all men have erection problems and erection problems certainly dont always occur. Erectile problems are common enough that theres a medical terminology to describe the problem. The specific medical term for erection difficulty is erectile dysfunction, or ED. As theres a medical term for erection difficulties, theres also naturally enough pharmaceuticals available to treat the disorder. Pharmaceuticals for the treatment of erection problems in fact have nearly become household names, with the Viagra brand leading the way.
