Toilet water splash back!!!

Okay at work today I finally broke down and used the work restroom.. it flushed automatically, so anytime I slightly moved from the sensor the damn toilet would flush. So as I’m Sitting, it flushed like three times in a row..

And each time it kept splashing me on the anus and vagina. I’m seriously grossed out. I have OCD so now I’m terrified that I’m gonna catch some sort of STD or HIV this way. Is this possible?! Help!!
