Can i get pregnant from swallowing cum or get pregnant with cum on fingers and fingering?

Swallowing: no: Fingers: yes. Only if fresh semen managed to get from her mouth into her vagina (not via the stomach or intestines inside her body), does she have any chance of getting pregnant from that adventure. Couples engaging in sexual adventures do get pregnant from time to time, so should be ready to be married, settled down, and with jobs that provide health insurance (babies have many doctor visits).
