Reassurance

Alright, I honestly just need some reassurance so please no hate. My boyfriend and I have never had sex, but we've done sexual things resulting in him cumming on his own. Before he came, he rubbed his penis on my vagina but didn't come on or in me. Is pregnancy even a remote possibility from this? I know that precum can cause pregnancy at times, but isn't that only if the man has came in the past 2 hours?
