I'm waiting for someone who actually suffers from this phobia, to chime in and point out how cruel you all are for POO-POO-ing this terrible affliction.
Well, I don't personally ahve a problem with using public facilities, but I do have recurring dreams about going into a public bathroom which has water all over the floor and bits and pieces of wet toilet paper on the floor. Often the dream goes back to the first public school I was in, an old yellow-brick building with the toilets in the basement. It's sort of humorous, as I cannot remember the bathrooms there being dirty at all. So it's a strange sort of bathroom phobia, but only in my dreams.
I also think it's a female thing. you guys just do not appreciate how much easier you have it with public bathrooms. HaHa! Boo Hoo!
