<s>[INST] I recently lost my virginity but of course I wore a condom. The last few times I masturbated I've noticed that my semen is a light green color like snot. This has been a problem even before any sexual activity. How can I fix this problem and should I be worried? [/INST] dear Sir.. the cause of the green colored semen is due to the presence of pus cells or bacteria in semen, most probably due to prostatitis...you need to see a doctor and get examined </s>
