In regards to sexual energy exchange-- As individuals, we dont NEED sex to survive so what's our motivation for engaging in sexual activity with another person?" If it's JUST for pleasure, so be it. If sex is deeper than pleasure to you AND you understand that energy gets exchanged, ask yourself WHY YOU WANT THAT PERSONS ENERGY and WHY you're willing to share yours. Sex, beyond pleasure is for connection, healing and creating, so what are you connecting, healing, creating...with them?
