Paul replies:My girlfriend and I were messing around in her room when I released "pre-cum" and she touched it. As she remembers she wiped it on my boxers and then fixed her panties because they were crooked or whatever. She is afraid that from the "pre-cum" on her panties she might get pregnant is this possible? Also I read that not always does "pre-cum" have sperm it will if you haven't pee'd between your last ejaculation and the next "pre-cum". Is that correct and is she safe from pregnancy?
Jacob,
Precum is a slick, clear fluid that drips out of the penis when it is excited. It's made by something called the Cowper's glands. Think of it as nature's own form of sex lube. Precum also helps to neutralize or deacidify the urethra (the tube through your penis that you pee and ejaculate out of). This makes it easier on semen during ejaculation. Precum also makes the walls of the urethra more slick so the sperm has less resistance.
Precum is not part of your ejaculation and it does not naturally carry sperm. However, that doesn't mean there aren't sperm that find their way into it, which is one of the reasons why having intercourse and pulling out right before you ejaculate doesn't always prevent pregnancy.
Your girlfriend's case--precum on the panties--I'd try not to lose a whole bunch of sleep over. While anything is possible, it doesn't in my mind rate a lot higher than the chances of a meteor crashing into the planet and sending us all the way of the dinosaurs. On the other hand, you won't know until you know, but I don't think the chances are very high at all.
Let me know what happens!
