QuestionI am an 18 year old male. For the last few years I have noticed a few droplets come out from my penis without my control. Is there any way to stop them?
There are three liquids which comes from the male penis. Since the sources of these liquids are internal, there is nothing forcing the liquids out of the penis except for the pressure supplied at the source and gravity. Just like a garden hose attached to the faucet at a house turning on the pressure causes water to come out quickly, but even after the faucet is turned off, water continues to dribble out for a while.
Urine comes from your bladder. Even after you finish peeing, you should wait a few moments to allow any remaining droplets of urine to exit. Gently shaking the penis sometimes gets the last droplets out.
Pre-ejaculate, or pre-cum, comes from your Cowper's glands. These glands produce a clear liquid whenever you get aroused. The purpose of the liquid is to clear out any leftover traces of urine in the urethra. The fluid is very slick and also serves to lubricate the urethra and the end of your penis in preparation for sex. The only way to stop this liquid is to keep it from being produced, which means to stop being aroused -- which isn't going to happen. It is just something guys learn to live with.
Semen comes from the ejaculatory duct. It is a blend of several liquids which are mixed and then ejaculated when a man reaches orgasm. It is a thick white or slightly yellow liquid. Most comes out in ejaculation, but a little gets left behind and dribbles out later. Again, there really isn't much which can be done about the later dribbles other than expecting it to happen.
