its possible but the chances are slim.

Depends on how long his hand was out in the air for.

Sperm can usually live up to seven days when they're in the cervical mucus of a woman's vagina. However, when they're not being nourished and protected by cervical mucus, vaginal secretions, the warmth and moisture of a man's urethra and reproductive tract, or other warm and moist conditions, they die anywhere between a half an hour to four hours.

If he puts his fingers inside of you with sperm on them you can get pregnant. I would wash with soap and water before hand to be safe.

If the semen is still wet there is a chance it has ssurvived, but there is a VERY slim chance of getting pregnant. To be sure, Wash your hands with soap and water like death_cutie said
