Sperm can live outside the body up to 72 hours but since he washed his hand I don't think you would have gotten pregnant but I would get checked out to make sure
There is no way ATALL that you could possibly be pregnant, there is no way that sperm can leave the body stay on his hands and then be inserted into you, sperm dies as soon as it leaves the body, and is released into air, if you did have full on sex then yes, there would be a chance, but there is no way through fingering you can be pregnant x
thank you guys so much! im a little bit more calm now
