Adjectives that don't even apply to promiscuity, that's your bias.

Let me take a wild guess where that bias came from... hmmm. Maybe, just maybe you talk to a dead rabbi who lives in the sky and hates sex even though he rarely brought it up while he was alive.

Try 180,000. All hunter-gatherer tribes had no concept of marriage. History has no record of it until 4000 years ago. It's a very new concept for humans to selectively pair bond for life.
