Sometime my semen is yellow if I havent masturbated in a while. Semen changes colours for lots of reasons. I think the main is body temperature and length between ejaculations. If you don't ejaculate for a week you'll probably see the semen is darker, where if you masturbate often, the color becomes clear. If your semen remains light green, see a doctor as you might have a infection.
Hi D, The most common causes of yellow semen are urine, age, diet and infection, so just get off to your doctor and take a sample with you, but a freash one just before you go.
Good Luck
Thanks Both for your comment
I really appreciate it.
I will do a check up just in case.
