Once again, the guys are also right. (And they should be.) It will start to turn milky, until you're fully producing sperm.
Until then, as a female who ends up swallowing or having c*m on my skin... Here's some fun facts. Semen, though milky/white in color, is not a milky texture. If you're just masterbating (and I assume eventually having SAFE sex), the consistency will be very viscous... Just gross, sticky, gooey... Because the vaginal mucous contains anti-coagulating enzymes. Which your semen obviously won't come in contact with unless it's in a girl's vagina without a condom. Also, what you eat will determine the "flavor" of your semen. So when you start getting blowjobs, it would be nice of you to drink some juice if your girl is gonna swallow. Because it really does not taste good.
So some advice... Don't c*m on your future lady or in her mouth unless she says it's okay. Because not only does it feel gross, it usually tastes gross. But women generally only swallow if they love you. Or if they're sluts.
