I think a very important thing to note here is this:
If you put a penis in a girl when you were hard, and anything came out, and especially of you ejaculated (cummed, nutted, etc) inside of her, then .y.e.s she can very well become pregnant.
Women who are raped certainly don't orgasm, but they become pregnant. A woman's orgasm has nothing to do with getting pregnant; it just feels good.
