Yes to reproduce is one of the instincts we have, but there are also pack instincts to survive and help one another. There are benefits to relationships with other people. I suppose orgies might be benefical in that way if you all support one another, however I would worry about the risk for diseases. Anyhow, just a thought. I am not interested in orgies, though so quit asking. I don't think they would benefit my husband or me at this point in our lives. Plus we don't live in California.
