I've never thought about OCD and personality traits thereof, but I'll just list some of mine, of which I think may relate to my OCD:

• Difficulty in accept sufficiency.
• Prone to feeling guilty.
• Heightened sense of responsibility.
• Moralistic. Firm unwavering beliefs.
• Creative - I've read that OCD and creativity pair very well together.
• Stubbornness.

S'pose that'll do. Dunno if that'll help at all, but thought I'd give it a shot.
