A spontaneous shift in sexual orientation from homosexual or bisexual to heterosexual is by far the most common change that occurs in sexual orientation. Numerous studies have shown that both religiously and secularly mediated change in sexual orientation occurs in highly motivated, dissatisfied homosexuals at a rate that is at least comparable to the success rates generally achieved by therapists and counselors for other behavioral problems. And many studies have found that, for the most part, these are long-range, stable shifts in sexual orientation.
