Normal sperm?

I was masturbating and when I climaxed I had thick chunky semen come out. It looked like spoiled milk. After the first initial squirt the semen returned back to normal. What could this be? I think maybe old semen was backed up and I shot it out and that's why the rest was normal?

Hello,
Chunky or clumpy semen is normal and is not a symptom of a sexually transmitted infection (STI). Semen (a.k.a. ***, ejaculate) can vary in texture, odor, color, and taste. After ejaculation, proteins contained in semen can cause it to become thick, sticky, and clumpy. Since it was followed by normal ejaculation, there is nothing to worry.
