HOCD (Homosexual Obsessive Compulsive Disorder) is a debilitating condition that attacks without warning in those who already struggle with classic OCD. It leaves its victims reeling with uncontrollable doubt about their sexual orientation (despite never having questioned it before), while igniting a vain pursuit of certainty over the question of whether they are truly straight. In this HOCD primer, Andrew Rosen, Ph.D. draws on more than forty years of clinical practice to give readers insight into the disorder, as well as offering practical help to those who are fighting against a sexuality they know deep down really doesn’t exist for them.
