Optimal male sexual health includes sexual desire (libido) and the ability to get and sustain an erection (erectile function). Although physiology can affect both the desire for sex and the ability to have sex, mental health and emotional factors also play important roles.

Male sexual health isn't merely the absence of disease. Erectile dysfunction (ED) is the inability to get an erection or to maintain it long enough for satisfying sexual activity. Many things can cause ED, including stress, depression, relationship issues, abnormally low testosterone, damage from urological surgery, and even cholesterol-clogged arteries. In fact, it is often an early warning sign for heart disease. ED can be treated with pills, injections into the penis, or devices.  Men can also experience difficulties related to ejaculation, including premature ejaculation, delayed ejaculation, or the inability to experience orgasm upon ejaculation (anorgasmia).
One of the best ways to improve your health is cardiovascular exercise. Sex might get your heart rate up, but regular exercise can help your sexual performance by keeping your heart in shape.

Thirty minutes a day of sweat-breaking exercise, such as running and swimming, can do wonders to boost your libido.

Stress can affect all areas of your health, including your libido.

Stress increases your heart rate (in the bad way) and increases blood pressure. Both of these are damaging to sexual desire and performance.
