Relation between child molestation and ity? What made me a gay person?

What difference does it make? You are gay, you are out, so how about focus on being a family with your parents loving you and supporting you? If they cannot do this until they know what "caused" your being gay, perhaps family therapy will help everyone focus on the future. The ual abuse you suffered is something worth discussing with your individual therapist...not for any effect it had on your ual orientation but because it is trauma and will likely affect you in future relationships.
