I spat out semen, rinsed mouth, kissed my bf, he took a shower then i ate 2 slices toast he took 1 bite and we drank soda 20min later we kissed again and he went down on me could i get pregnant from any sperm residue in his mouth from the first kiss?

Wouldn't think so: That hypothetical scenario alone should not lead to a baby (0% chance, mathematically rounded). In general, if a woman is able to get pregnant with fresh sperm straight from a penis, then she is also able to get pregnant with fresh sperm via a tongue or finger. However, a penis can put a much larger amount of semen right at the cervix. Tongues and fingers are better suited for other activities.
