Last night I used a public restroom. I squatted so that I wouldn't have to sit on the seat as there were no toilet seat covers an then I realized that as I was using toilet paper to wipe, the toilet paper touched the seat before I wiped my genitalia(I'm female. If the toilet paper did pick up some urine on the way and I basically wiped someone else's urine onto my vulva, is it possible for me to get any diseases from this?
