Both men and women may experience a skin flush. I feel like I've been hit by lightening or touched an electrical socket, but after about 10 seconds, I relax quickly and the tension flowing out of my body is such a relief. The hypothalamus tells another part of the brain to release hormones into the blood stream. There are several sex hormones including oxytocin, dopamine, norepinephrine, endorphins, estrogen and testosterone. Hormones are brain chemicals that play a large part in our development, our behavior and our feelings, by transmitting neural signals from neuron to neuron.
Endorphins act like morphine and are the body's natural painkillers.
Endorphins go to work when we exercise, have sex or hang around a loved one. They result in a feeling of well being and contentedness. Dopamine and noripenephrine are at work when you feel the giddy high of love and attraction. Dopamine also stimulates the production of oxytocin. Oxytocin may play a role in the emotional attachment between people, and it also makes females sexually receptive.
