I believe that my bathroom and everything in it is full of germs; I also believe that my body has been perfectly able to deal with those germs for the last 40 years, as I don't really get sick besides the yearly-or-so cold or flu.

Taking my toothbrush out of the bathroom for the fist time at this point in my life because of "the germs" would be paranoid behaviour, in my opinion. It's not that there aren't germs, it's that they've always been there and I'm still here and healthy.
