pnj4life. my roomate in college got pregnant because she and her b/f were "naked grinding" and he ejaculated on her pubic mound/tummy. she swears to this day that he never entered her and that her baby was conceived by only that (which she also swears that she never saw any ejaculate in or near her vagina).
the bottom line is that if you don't want to get pregnant, you have 2 choices. 1 is to have NO PENIS get near you, and the other is to have NO UNCOVERED penis get near you.
it's pretty simple. for your benefit, i'll pray that you are not pregnant and i do wish you the best of luck. just don't get any uncovered penis NEAR YOU in the future.
