the only thing i want to point out is that the chances of getting pregnant off of precum are very small. precum first of all has no sperm in it. second, the only way it would have even a tiny amount of sperm in it is if you ejaculated, then precummed into a chick right after (WITHOUT PEEING IN BETWEEN!). urine kills sperm. the chances of getting your chick pregnant off of precum is remote (VERY remote). however all it takes is one intrepid sperm. also, it seems (based on research) that the millions of horror stories of how a mans penis looked at a vagina and got it pregnant seem to either be exaggerations, or more of an urban myth. people seem to know tons of people that were born of precum, while the numbers dont really support that. you have to remember, people still use the rhythm method. thats actual ejaculation into a woman when she is least fertile (not effective, but thats still out there...)
i feel like im about to cause like a million unwanted pregnancies. however, you guys do need to be educated, beyond 8th grade health. if you just think that whenever you put your member up there, all it takes is one lonely sperm to get your biddie knocked up, then you will WANT to be safe. however, so you dont absolutely go insane waiting three weeks for your chick to go back on the rag, take a deep breath, realize the chances are tiny, and think about your agony next time you want to play just the tip without protection.
