Sexual orientation compared with sexual orientation identity

The American Psychological Association states that "sexual orientation is not a choice that can be changed at will, and that sexual orientation is most likely the result of a complex interaction of environmental, cognitive and biological factors...is shaped at an early age... biological, including genetic or inborn hormonal factors, play a significant role in a person's sexuality". They say that "sexual orientation identity—not sexual orientation—appears to change via psychotherapy, support groups, and life events". The American Psychiatric Association says that individuals may "become aware at different points in their lives that they are heterosexual, gay, lesbian, or bisexual" and "opposes any psychiatric treatment, such as 'reparative' or 'conversion' therapy, which is based upon the assumption that homosexuality per se is a mental disorder, or based upon a prior assumption that the patient should change his/her homosexual orientation". They do, however, encourage gay affirmative psychotherapy.
