No she cannot get pregnant that way.
You're not likely to get her pregnant if you had cleaned your hands thoroughly.
if a guy cums on his hands then wipes if off with a towel and then fingers the girl like 10 minutes later can she get pregnant?
I think you're safe
She may be pregnant, but probably not as a result of the activities that you described.
It is highly unlikely.
No; if the pre-cum didn't die by the time you washed your hands, and you wash thoroughly, it'll be rinsed off and you won't get pregnant.
You can still have sex if she is pregnant. It is complete myth that it is dangerous for the baby. At the later stages she may not feel like it so if needed, do it yourself.
if he still had some sperm on his hands. yes.
