OCD: Common Obsessions 

Abstract Man

"Pure-O", "Pure Obsessional" OCD: Covert Compulsions

For many sufferers of OCD, their compulsions take the form of covert & mental compulsions, rather than overtly observable behavioural compulsions. This form of OCD was once thought to be rare (where in reality most sufferers of OCD present with at least some mental compulsions) and was mistakingly viewed to be a "Pure Obsessional" form of OCD due to the lack of recognition of sufferers' unobservable covert compulsions.

Gender & Sexuality Obsessions

OCD sufferers often ruminate compulsively to the point of uncertainty and confusion, creating fears and a false sense of doubt around their gender and sexuality, worrying that they are lying to themselves about their true sense of self which can feel destabilising. These obsessions are driven by a fear of uncertainty, or e.g., a fear they are "bad for lying to their partner about their true sexuality" rather than their values around gender and sexuality.

Somatic & Sensorimotor Obsessions/Compulsions

Another form OCD can take is obsessive attention and hypervigilance to bodily sensations, such as swallowing, breathing, genital stimulation, health concerns, or uncomfortable sensory urges. More info coming soon.

Incompleteness, "Not Just- Right Experiences", & Sensory Phenomena.

What separates OCD from anxiety disorders, is in part the presence of tic-like sensory phenomena reported in 65.1% of sufferers, as well as the uncomfortable experience of something not feeling, looking, or sounding "just right", creating discomfort and driving repetitive behaviours to neutralise these uncomfortable sensory urges or sense of "incompleteness" (rather than compulsions driven by anxiety).
