            <p>The calculations provided are rough estimates and should not be considered medically or scientifically accurate. Masturbation should not be relied upon as a primary form of exercise or weight loss.</p>

            <p>The intensity levels (light, moderate, vigorous) are subjective and their impact on calorie burn is an approximation. Individual experiences may vary significantly.</p>
