Sex 4.0 is a term used to describe what some believe is a modern day sexual revolution taking place right now. Much like past sexual revolutions, such as those in the 20s and 60s, the Sex 4.0 revolution is pushing boundaries when it comes to sexual practices that were previously thought of as taboo. The Sex 4.0 revolution is all about embracing your sexuality and exploring your sexual desires in a safe manner with consenting adult partners. Today, everything from bi-sexual encounters to male sex toys to fetish play is now becoming the norm.
