But when i used to masterbutethe color fo the siemen became pale yellowwhat is the reason behind it?

Answer 1

While semen usually appears white, it can be somewhat yellow. I have seen this confirmed in a few references on websites. In my personal case, it was yellowish, darkest the first time I discovered masturbation at 13 years old. The next couple of times it was gradually lighter, and white thereafter. At 19 years old I joined the Army, and during Basic Training went about 8 weeks without the opportunity for a moment of privacy. When I did get a chance to masturbate, the discharge was again yellowish. I firgure it must get yellow if it "ripens" a certain length of time, but is then white when you flush it out regularly.
