A lot of people here don't seem to have a great understanding of precum. Which is ok! But I wanted to explains bit. Precum -or preejaculate- is a fluid the penis secretes as lubrication. It is a body fluid that is not sperm, but does contain some sperm cells. It is possible to become pregnant from this small amount of sperm cells but it is HIGHLY unlikely. A typical ejaculation has around 300 million sperm whereas precum typically contains a couple hundred. So we can stop worrying quite so much about about becoming pregnant from it. Hope this helps!
