I gave my boyfriend a hand job, he ejaculated, went and took condom off, washed it off with soap\water and then came back and fingered me. pregnancy?

Almost impossible: The odds that viable sperm could withstand the likely spermicide in the condom, hand-washing and being outside the male/female reproductive systems for that length of time, not to mention then having to navigate your female reproductive tract to lead to fertilization are like winning the lottery. I would be more worried if you became pregnant that the condom broke.

If he washed : his hands thoroughly, this should not lead to pregnancy.
