1. Get moving
As cliché as it sounds, exercising is one of the scientifically proven ways to improve your libido. You need to understand that exercising is much more than just going for a walk. Do whatever works the best for you, whether it is sweating it out in the gym or going for a run in the morning.
Additionally, you may also try pelvic exercises like Kegels for more benefits. However, do not forget to have a word with your doctor regarding the same.
