), colloquially known as sex drive, is a person's overall sexual drive or desire for sexual activity.Sex drive is influenced by biological, psychological and social factors.In the week following ovulation, the testosterone level is the lowest and as a result women will experience less interest in sex.Also, during the week following ovulation, progesterone levels increase, resulting in a woman experiencing difficulty achieving orgasm.Failure to adequately adapt to the demands of these different stages could result in libidinal energy becoming 'dammed up' or fixated in these stages, producing certain pathological character traits in adulthood.
A person who has extremely frequent or a suddenly increased sex drive may be experiencing hypersexuality, while the opposite condition is hyposexuality.
These factors can include lack of privacy or intimacy, stress or fatigue (medical), distraction or depression.
Environmental stress, such as prolonged exposure to elevated sound levels or bright light, can also affect libido.
Although some specialists disagree with this theory, menopause is still considered by the majority a factor that can cause decreased sex desire in women.
The levels of estrogen decrease at menopause and this usually causes a lower interest in sex and vaginal dryness which makes intercourse painful.
