Not at all, wrap the toilet like a mummy with tp, squat/hover in a weird way to not touch it?
I personally refuse to use public toilets but if I have to, then I wrap it and hover over it lol. I cringe when dd1 has to go. I'm just the super germaphobe mom. They say it doesn't really matter if you use them as long as you don't have any open wounds, but still it's just ewwww to me.
