Loss of sex drive (also known as libido) is when a person has a reduced interest in sexual activity or sexual thoughts.
Losing your sex drive is common. It can be linked to a number of factors, including relationship issues, stress, anxiety, some medical conditions and side effects of medication.
Everyone's sex drive is different and there's no such thing as a "normal" libido. But if you find your lack of desire for sex is distressing or it's affecting your relationship, it's a good idea to get help.
