In class we talked about sexuality and the importance of having intimacy in a relationship. The most important sex organ is the brain. The brain produces three hormones, which are seratonin, dopamine, and oxytocine. Seratonin is the hormone that makes you happy, Dopamine is a neurotransmitter for excitment, and oxytocine is released through touching. Sexual relations release a good amount of seratonin. Safety, comfort, love, and confidence is the key to successful sexual intimacy.
