Need some help

gonna keep this short
I was receiving head and before nutting I pulled it out and nutted in my palm,went up and wash my hand hands throughly (without soap) .

Then we made out and did a lot of cuddling and after 5 min or so i fingered her slightly

Now this was my first time so am asking
is there any way that any microscopic sperm left that could enter her vag through my hand
