Talk to Gynecologist on Sperm/sexual Activity

Please clear me here, there are a lot of myths that you can get pregnanct if the sperm is near /around your vagina , But can you also get pregnant if the sperm is somewhere around the belly and you r washing itwith water? Bcz if water comes down While washing the sperm can touch vagina ,I also Inserted my finger to clean if incase the sperm is near the vagina whole .. Is it possible to conceive with the sperm mixed with water , the way I explained above?
