I have a huge fear of pubic lice. I used to just lay down 3 or 5 sheets of toilet seat covers whenever I was in a public restroom. I still felt very uncomfortable but I found it in me the strength and courage to just pinch a loaf off. However, I was in the park one day and I really had to defecate. Surprise there were no toilet seat covers. I didn't know what to do though so I just tried to do it the urinal. I was really scared somone was going to walk in though and I couldn't go. So I zipped up my pants and started to walk out when my stomach quaked and I quickly ran toward the urinal and defecated my intestines out. I thought it was pretty funny afterwards, though, and began to do it at school and work too. It's the only thing I do now when I have to poop away from home and I really enjoy it as it feels much more releiving. I kind of feel bad about it though because someone has to clean it up but I just can't stop. Is this a normal thing, or maybe a phase?
The toilet seat is actually the cleanest part of a bathroom. The material it's made out of is non-porus, so there's no place for bacteria to grow. Don't take my word for it, there's an episode of the show "Mythbusters" where they took samples and made bacteria cultures from them. The toilet seat was actually cleaner than the kitchen table.
There seem to be a lot of fake stories today.
If anyone did this though, I'd hope they got forced to clean it up a whole bunch of times.
Public bathrooms are usually cleaned twice a day. And as someone else stated before, toilet seats are non-porous and therefore bacteria has a difficult time growing on them.
It's also extreamly rare to contract pubic lice or any VD's from toilet seats. If you're still weirded out just put toilet paper around the seat or one of those toilet seat guards that many bathrooms provide.
