Although we can choose whether to act on our feelings, psychologists do not consider sexual orientation to be a conscious choice that can be voluntarily changed.
What causes a person to have a particular sexual orientation?
There is no consensus among scientists about the exact reasons that an individual develops a heterosexual, lesbian, gay, bisexual, transsexual, queer, asexual, pansexual orientation. Although much research has examined the possible genetic, hormonal, developmental, social and cultural influences on sexual orientation, no findings have emerged that permit scientists to conclude that sexual orientation is determined by any particular factor or factors. Many think that nature and nurture both play complex roles; most people experience little or no sense of choice about their sexual orientation.
