Obsessive Compulsive Disorder (OCD) Support Group
Obsessive-compulsive disorder (OCD) is a psychiatric disorder, more specifically, an anxiety disorder. OCD is manifested in a variety of forms, but is most commonly characterized by a subject's obsessive (repetitive, distressing, intrusive) thoughts and related compulsions (tasks or rituals) which attempt to neutralize the obsessions.
I can't relate to your second point but on forums I've seen a lot of people talk about the intrusive sexual thoughts.
