DNA Transfer Apertures

Youth gets especially excited about sex.  How come sex is pleasurable?  Because YOU, the operating system , don't get it that the millions of cells want to reproduce and YOU are the only channel they have.  So we have data transfer apertures for DNA code and a kind of pleasant madness that seizes us to make sure we use them.    Manimals and feminals want into the future, even if you don't.

The longer we live, the less sex is actually needed to keep the species refreshed since each baby lives longer, and can have more wealth and influence than a big had family back in the day.

Personality, the Me-Myself-And-I, has leverage in the world but thinks itself above the humble system it populates.  That system keeps a couple billion cells and their organs fed and safe.  We Jacks and Jills can skip the priorities of reproduction but our body doesn't agree.  The humble system has fixed it so we get excited by touching near DNA transfer apertures, to lure us into doing something useful for the future.
