Although this may be true for a portion of men, the vast majority of cases have now been identified to have a physical cause or correlation. If the sexual dysfunction is deemed to have a psychological component or cause, psychotherapy can help. Situational anxiety arises from an earlier bad incident or lack of experience, and often leads to development of fear towards sexual activity and avoidance which enters a cycle of increased anxiety and desensitization of the penis. In some cases, erectile dysfunction may be due to marital disharmony. Marriage counseling sessions are recommended in this situation. Lifestyle changes such as discontinuing tobacco smoking or substance use can also treat some types of ED. Several oral medications like Viagra, Cialis, and Levitra have become available to alleviate ED and have become first line therapy. These medications provide an easy, safe, and effective treatment solution for approximately 60% of men. In the rest, the medications may not work because of wrong diagnosis or chronic history.Another type of medication that is effective in roughly 85% of men is called intracavernous pharmacotherapy, which involves injecting a vasodilator drug directly into the penis to stimulate an erection. This method has an increased risk of priapism if used in conjunction with other treatments, and localized pain.Premature ejaculations are treated by behavioural techniques Squeeze technique and Stop Start Technique. In Squeeze technique the area between head and shaft of penis is pressed using index finger and thumb just before ejaculation.
