Remember learning about the fight or flight response? We may not be running from saber-tooth tigers anymore but our bodies still take stressors very seriously. Simply worrying about money problems or relationship issues can affect your sex life. When stressed, your body releases hormones, like cortisol and adrenaline, which can reduce your sexual desire and clamp down on your arteries, making it harder to get hard. Yoga, meditation, and therapy all have some scientific support showing they can help de-stress your sex life.
