~This probably means you aren't ready. You didn't say how old you are, so I'm assuming you're very young. Another way I can tell is that you have clear stuff coming out, not white. When you're older, your semen will turn white. Usually, you ejaculate into a rag or tissue.
Don't rush it, when you're ready, you'll know.~
