The consumption of chocolate, whether it's dark or regular, basically releases a rush of endorphins in the body, the group of hormones responsible for producing pleasure. Dark chocolate is the healthier kind of chocolate and does help boost dopamine levels in the brain, but it isn't a cure or remedy for any sexual problem. Enjoy it in moderation, and indulge in warm cups of hot chocolate during date night, but don't have any unrealistic expectations from it!
