Question

[paki123]

Is your sperm suppose to look yellow when its on a white towel? Because when i ejaculate it looks white, but when i clean it up off of me its yellowish and real thick

[Trademarked]

it's just your pee coming out. cum and sperm use the same track, so there might be some urine in there.

[Antares]

unless its really not white when it comes out

Its not pee, cum can range from pure white to dark yellow. My cum appears slighty yellow on paper too

Appearance and consistency of human semen

Most semen is white in colour, but grey or even yellowish semen can be normal as well. Blood in the semen can cause a pink or reddish colour and may indicate a medical problem which should be evaluated by a doctor.
After ejaculation, semen first goes through a clotting process and then becomes more liquid. It is postulated that the initial clotting helps keep the semen in the vaginal canal, but liquefaction (http://en.wikipedia.org/wiki/Liquification) frees the sperm to make their longer journey to the ova. Immediately after ejaculation semen is typically a sticky, jelly-like liquid often forming globules. Within 5 to 40 minutes it will become more watery and liquid before finally drying.
