Esther Perel is a renown Belgian sex therapist with a passion for understanding sexuality and long term, committed relationships.
In her TED talk, Perel speaks of the the difference between love and desire, and the conflict we have as human beings between being safe, secure and needed by a partner, versus the mystery, attraction and freedom that fuels passion.
It is a perfect message for Valentine’s Day. Enjoy.
