What is precum, exactly?
When not using a condom or other barrier method during sex, liquid from the penis can enter the vagina without either party knowing. Even with the best form of protection, it is always possible that sexual intercourse can result in an unintended pregnancy. In this article, we discuss precum and the risk of getting pregnant from this preejaculate fluid. Before ejaculating, the penis releases fluid that people many call precum, or preejaculate. Precum comes out involuntarily before ejaculation. The fluid is partially for lubrication.

Precum itself is a lubricant, but that does not mean that it cannot transport semen or sperm from the penis to the vagina. Precum is also not voluntary.
