Semen doesn't come from the Elmer's glue factory. You look different than every other person on the planet why would your semen look the same? Some is thicker or thinner, some whiter or more yellow, some more clear, some more opaque. Really don't compare your semen to others, not healthy.
If you're under the age of 19 you're not done sexually developing. Don't get upset by any aspect of your sex organs that isn't causing your pain or bleeding.
