Libido refers to a person's overall sexual drive or desire for sexual activity. It is influenced by various factors, including biological, psychological, and social elements. Hormones, such as testosterone and estrogen, play a significant role in regulating libido, while mental health and relationship dynamics can also impact sexual desire. Libido can vary widely among individuals and can change over time due to stress, health conditions, or life circumstances. Understanding libido is important for addressing sexual health and well-being, as it can affect personal relationships and overall quality of life.
