I too have what has been termed "Pure-O", but that's kind of a misnomer. Rituals don't have to be physical actions to be classified as compulsions. I usually get stuck simply trying to mentally disprove my obsessions, and that is a compulsion. I don't wash, check or do any of the things that people on TV with OCD do. I think you will find that this type of OCD is quite common as you read more posts here. It seems to go undiagnosed a lot of times because there are no outward signs of it.
