Being gay, lesbian or bisexual isn’t a disease, so you can’t be ‘cured’. There’s no scientific evidence that anything can change you from being homosexual to being heterosexual. It’s just the way you’re made. People who are unhappy about their homosexuality, perhaps for religious reasons or because of social and cultural pressure, sometimes learn to suppress their sexual feelings.
Some people try to change their sexuality through therapy, exorcism, or religious rituals. These can have very damaging effects, and none of them provide a ‘cure’. Many doctors and psychologists have spoken out against this ‘conversion’ or ‘ex-gay’ therapy. These programs hurt the person who goes through them, and they can’t do anything to change a person’s sexual orientation.
