Probability is high. Why have unprotected sex when all your generation tells us day and night is how educated in sex and reproductive health you all are? There is no good reason to screw without bc pills or rubbers on the penis. None. Why put yourself through this worry...don't get it. Withdrawal method...in this day and age? I guarantee you that some cum from him got into your vagina, now if you're not pregnant, thank the Lord above.
