URGENT FREAKING OUT Can you get an std or any infection this way???????

So.. I had an abdominal ultrasound today for my kidneys.

But, the doctor was in hurry, so he forgot to change the paper on the bed.

Can i get an std in this way? My butt cheeks touched the old paper the previous patient was on. I wasn't naked, i was wearing my underwear, but my naked butt touched the bed. I'm so scared. I wiped my butt cheeks with antibacterial wipes but i think that will do nothing.

Also, i think im gonna have sex tonight, so he will touch my butt and then my pussy and it will spread like crazy.

Im sooo scared. Please noooo rude comments. Please just help
