Very inexperienced person here. This isn't trying to troll or anything and is a honest to goodness question out of curiosity.

Somewhat more recently in some porn videos I have seen what looks like some really white liquid coming out of a woman's vagina, at first I thought ehh it's a creampie scene answers that. But then I noticed no way is that it because the color and amount was in no way what an ejaculation would be like. So I then thought must be something they add in porn for more visuals. However I have also seen things like this in solo masturbation videos and then in much more amateur pictures and videos. Often times in a video it is described as "creamy" just writing that makes me shudder because it sounds so unusual. What on earth is this? If it is just part of natural lubrication, how come this only seems to happen sometimes? Like if I had to describe it I'd say it almost is the color of Elmer's glue. If it is something else please let me know as well as what is the purpose of this liquid. I feel somewhat stupid for asking but then again you'll never know unless you ask.
