There are several factors that can cause high sex drive in females, including changes in hormone levels, age, exercise, and lower stress levels. Specifically, estrogen levels rise before and during ovulation, causing an increase in sex drive in women. Additionally, being on estrogen therapies, like for menopause or bone loss, may be the reason for a higher sex drive in women. High levels of testosterone are also linked to higher libido in men. However, its important to note that there is no "normal" sex drive, as everyone is different and our bodies behave in different ways. If a high sex drive begins to interfere with ones life, work, or relationships, it may be worth discussing with a doctor. Other factors that can affect sex drive include general health habits, stress, mental health, and certain medications.
