Thanks for your question. Pre-ejaculate (pre-cum) that is released before a guy climaxes is often clear. However, ejaculate or semen (cum) that’s released during orgasm is typically thick, whitish, gray or slightly yellow in color, and slightly transparent (you can see through it). It also feels a bit sticky. It’s interesting though because once semen leaves a guy’s penis, it changes and becomes thinner and watery. This usually takes about up to 5-30 minutes. So, if you are checking the color of your semen before ejaculation or afterwards, you may think your semen is clear, when in fact the color is normal. Either way, it’s a good idea to make an appointment with your health care provider. You can have a simple test called a “semen analysis” to see if your sperm are healthy.
