Ive masterbated recently and i got semen over my hands. about five minutes later, i used the same hands to open a door (this is before i washed my hands). if a woman opens the same door and touches her vagina after, will she get pregnant?

I think you've asked several similar quesitons, right? Of course no risk at all, and even your thinking is illogical. If such events could result in pregnancy, obviously there would be many pregnancies in virgin women. But that doesn't happen. Please stop asking similar quesitons. If you remain obsessed about this, you may need professional counseling. Good luck.

that would be very unlikely to occur
