Is There A Risk Of Pregnancy If My Female Cousin Touched A Toilet Seat Used By Males And Then Accidentally Touched My Vagina With The Same Hand?

My female cousin touched the toilet seat that my brother and my male cousin uses. She used that same hand to touch my vagina by mistake while sleeping carelessly. Is there any possibility of precum or sperm coming out while my brother and male cousin where peeing. And is there any chance of getting pregnant when my female cousin used that same hand to touch my vagina?
