Plugs

liquidindian: Well, do you want to know about mucus plugs?
cheesoning: nope
cheesoning: I'm married to a nurse.
liquidindian: I'll tell you anyway.
liquidindian: Rats, as you may know, have big balls.
liquidindian: That's because they're not monogamous. They shag around. Therefore, sperm competition.
bigjimslade: I'm married to a post/ante-partum nurse *and* have two kids. You cannot possibly shock me
liquidindian: But they also have something else, that shows the unidirectional nature of evolution.
cheesoning: nipples?
bigjimslade: can you milk them?
cheesoning: I guess nipples are directional.
liquidindian: At some point, a rat had a mutation where, after sex, it blocked the little rat vagina with a sticky mucus plug.
cheesoning: gross? This is getting HOT!
liquidindian: It prevents other rats from mating with that rat. So obviously this mutation has spread. It's a successful mutation.
bigjimslade: afk a sec, need to put my pants on a hook or something
liquidindian: But once you've gone down that route you can't go back.
cheesoning: so you're saying rats reproduce once and that's it?
cheesoning: or just mutant rats?
liquidindian: To get rid of the plug system would be disadvantage the first rat that did it.
liquidindian: So other suitors, before mating, eat the plug.
cheesoning: aw fuck. There it is.
liquidindian: And they're stuck with this waste of time and energy.
bigjimslade: thus oral sex was born
cheesoning: in a million years, you'll never guess what I was eating when you started this rat discussion.
bigjimslade: mucus plugs?
Cyrano: rat?
bigjimslade: vaginal secretions?
chrisd: pussy?
chrisd: damn, beat me to it
