There is nothing wrong with your penis, your testicles, or any of the associated "pipes and tubes."
Your ejaculate contains more seminal fluid, which is what nourishes your sperm. This fluid is also your "pre-cum." Pre-cum is released to neutralize the PH balance in the urethra and lubricate the penis. Your body just uses more seminal fluid in your orgasms, which is natural for some men.
There's really nothing you can do to thicken your come, and don't let porn taint your mind about what come should look like.
Think of it this way, if you're with a girl that likes to swallow, or be climaxed on, she'll get more for the work.
