if you had a microscope you would most likely find viable sperm happily swimming around in just about any fluid coming from the penis including urine after an ejaculation. the fluid that you see at the beginning of sexual activity that you call "precum" is seminal fluid and that too can have live sperm. after ejaculation there is plenty of rogue sperm still viable in any post-coital drainage. as an effective birth-control measure it is always best to keep the penis sheathed in a condom when it is near a vagina.
