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.
Some men with low testosterone have a normal libido, and some with normal or high testosterone have a low libido. Erectile dysfunction (ED) is sometimes associated with low testosterone as well, but low testosterone itself is not always the cause. Instead, reduced vascular function is a more likely cause of ED.
