Why does my cat twitch and run? My 7 year old female cat has suddenly started twitching her back, running around, stops, grooms herself, and starts running again. I have her on a flea treatment and my other two cats don't do this at all. She only calms down if I pet her or she gets in her basket.
Psychological Causes. The most common causes of low libido in women are not due to physical or biological causes. Psychological causes like poor body image, low self-esteem, depression, stress and physical or sexual abuse are among the top reasons why women have low sex drive.
Not necessarily. For both women and men, sexual desire or drive decreases gradually with age. However, testosterone, the hormone which primarily controls sexual drive in men, never stops being produced entirely. Some men in their 70s and 80s have an active libido even with decreased testosterone levels.
