Can cardio excercise help my sex life?

Yes.: Cardio exercise is part of an overall healthy lifestyle. Being healthy will not only help your endurance for sex, but should also help you overall sex drive. Eating a healthy diet, getting enough sleep and minimizing stress are also important parts of a healthy lifestyle. Make time for sex. Always practice safe sex (wear a condom to prevent infection and a birth control to prevent pregnancy!).

Possibly: Exercise has a lot of beneficial effects with sexual performance being something that could benefit.
