I have two questions. Please answer them separately, thank you.
1. After I masterbated, I usually wash my hands. But I am afraid that there might still exist some sperm alive on my hands. Is it possible that a woman touches what I have touched and somehow get pregnant?
2. After a masterbation, there might still remain some sperm inside my long prepuce. How long can sperm keep alive inside it? From the internet the answer varies from 5min to many hours.
Thank you.
