Pregnancy is not possible in above circumstances. Contraception remains otherwise key in avoiding undesired pregnancy and associated anxiety, specifically when intercourse becomes possible.

No. Sperms have to enter inside the vagina to cause pregnancy

Sperm dies in 3-5 minutes outside the vagina. You washed your hands, and had no skin to skin contact, all sperm is dead and not active. In future always practice safe sex to avoid pregnancy.
