If you experience a reduced interest in sex during menopause, this can be due to several factors. First, hormonal changes play a role. The sex hormones oestrogen, progesterone, and testosterone are the fuel for a satisfying sexual experience. They contribute to arousal, desire, the right mood, and a healthy vaginal flora.
When oestrogen levels decrease, your vagina may become less sensitive, making it harder to feel aroused during the same sexual activity. It can also lead to vaginal dryness and a longer time to become lubricated. This often makes sex uncomfortable or even painful (and can interfere with achieving orgasm).
Additionally, the decline in progesterone and testosterone levels (the hormones responsible for feelings of desire and arousal) can simply reduce your need for sex. Your libido may change during menopause, no matter how much you usually enjoy sex.
