Dopamine plays a crucial role in libido, but simply increasing it can lead to a paradox where individuals experience heightened arousal without the ability to perform sexually. This intricate relationship involves the autonomic nervous system, and relying solely on dopamine-boosting substances can be hazardous. Some natural supplements, like Maca, Tongkat Ali, and Tribulus, have shown promise in enhancing libido, but it's essential to consult a physician before considering any supplementation.
