It is healthy for an adult to come out in all areas of his life, including to important straight people, in order to provide continuity between his internal, private life and his external, social life. Coming out alleviates the anxiety and depression caused by the sense of inauthenticity that arises from hiding or disguising oneself. Closeted gay men are usually cautious and circumspect in their social discourse and relationships. After coming out, they inevitably affirm they are now more self-assured and that all relationships, including those with straight people, are more authentic and, therefore, more gratifying.
