Dry humping and dry semen?

hi, im 16 and yesterday me and my boyfriend decided to fool around instead of having sex. So all in all, i jerked him off, he came, and it was on the tip, and a little bit ran down his penis, i rubbed it all on his penis, and i little got on his finger, so he pulled his pants up, thwn i got up and got a rag, and i wet it, then i wiped his penis off with the wet rag and he said he wiped his finger off with the rag too, then he pulled his pants up again, then he ate me put for a good few minutes or so, then he put one finger inside of my vagina, and it was the one he had cum on it and he said he wiped offf, but im worried if i could still get pregnant? Please help me if you can? Ive had people tell me that once the cum is dried up or wiped away theres no chance to get pregnant, but i think i need someone to please tell me!? Thank you so so much
