pre-cum
pre-cum: also known as pre-ejaculate or pre-ejaculatory fluid, this fluid is made in the Cowper’s gland and comes out of the tip of the penis shortly after an erection. It is designed to remove urine from the urethra and coat the walls of the urethra to increase the changes of sperm surviving once they have been ejaculated. Some people with penises always have sperm in their pre-cum and others never do. Sperm that is found in pre-cum is not likely to cause pregnancy. Pre-cum can transmit sexually transmitted infections.
