The Jon Richardson thing was good, I thought it was really informative, and respect to him, he was great.
After seeing the 'exposure' technique thing, I've sort of being trying it on myself, but it's not really working. I guess it takes time.
As for the rubbing the toilet seat, I'm not obsessive about hygeine, but I would not have been happy doing that. It really IS unhygeinic, so I imagine it would have been very stressful for someone with severe hygeine OCD.
