Okay...but why does it form plugs? I mean...think about it...shouldn't it be expelled and go away? I'm not completely unfamiliar with sperm.
Or, is there some biological fact I'm missing like chameleon sperm needs to be able to "hold" for months at a time?
Is that how the second clutch happens? Some sperm was not in an immediately usable form? Sperm plugs are the stuff that's supposed to hang around for later use?
I'm just trying to learn.
