Struggling to understand your sexuality is absolutely normal. Growth and development occur in every facet of your life: in physical body changes, spirituality, career interests, your sense of self, etc., so it is only natural that growth and development occur in the area of sexuality as well.

It is most beneficial to pursue treatment through a support group or individual therapy with a professional specializing in trauma or sexual abuse. Past trauma has a way of causing difficulty in our present lives, so it is important to seek treatment. Recounting every detail of the abuse is not the goal of therapy. The goal of therapy is to gain a sense of control over your life as you acknowledge the trauma, and find ways to prevent the trauma from influencing your present. Therapy will help you live a healthy and functional life in spite of the abuse.
