Precum refers to a viscous liquid that oozes from the opening at the tip of a man's penis when he is sexually aroused. It is a clear, generally odorless and tasteless liquid that is released by the Cowper's glands. When a man is HIV-positive, pre-cum sometimes has the virus in it. Sometimes spelled pre-cum.
Sometimes when I masturbate I precum so much that I don't need any other lube.

Cum that you CAN get pregnant from. So, pulling out quick enough won't always work.
I should have worn a condom, I never knew precum could have an effect.

Get the precum mug.
That embarrassing spot that can form on one's pants, from dancing with a lady, even if no obvious erection is present. (See also premature ejaculation and pronatalist.)
My Dad said you can get precum oozing, just by dancing with a lady.

Precum can contain millions of sperm, a good reason for not playing around with arousing sexual feelings, or engaging in "outercourse, "early withdrawal," or other risky behaviors.
