I believe humans evolved using any and all materials from the environment including animal skin/sheddings, organ tissue, leaves, seaweed, stoppers including smooth pebbles wood/stems and anything else they could get their hands on as a form of daily accessible natural condom/birth control, in addition to the popular known methods of ovulation timing and pulling out, even diet based miscarriage techniques and manual abortion have played a vital role in human survival as men are designed to require sex at an absolute minimum of once every 2 weeks or else begin to have nocturnal emissions which only wastes both the pleasure of orgasm and viable sperm
