Since I have to squat to pee... I use to think living with a man and a men's restroom was the grossest thing ever until I go over to 98% of my girlfriend's houses and use their bathroom. Women are just pigs in general despite their upkeep habits.
When I use a public restroom it's 5x's as bad and I'm not exaggerating. Any normal time I carry a small pouch of baby wipes with me to grab doors. During the winter, I use my coat sleeve to grab the door handle just going in and open the door to the stall. I usually pull out layers of toilet paper just to cover my hand and wipe the seat down. Then I decorate the seat with layers of toilet paper like a christmas tree. After I've done my business, I wrap my hand just to open the door. Prop the door open with my left leg and flush with my right foot, as if I'm doing a split. Then I use the same toilet paper I've used to open and close the stall with to lift up or turn on the sink handle if certain places don't have the hands-free. Because I've used so much toilet paper on the rarest occasions, I have only clogged the toilet twice and plunged it myself at two various hotels I stayed at.
The only store I've ever been to that cleans their bathrooms every hour is Target. They are REQUIRED to keep the bathrooms clean and sanitary as much as possible. The worst are rest areas, convience stores, travel centers and gas stations. I will hold it in until I bust before I will ever go to those places EVER again.
I didn't become this germaphobic until I found out I was pregnant years ago.
