Men dating younger women formula
Women with typical genetic development are usually capable of giving birth from puberty until menopause.
With regard to gender, a woman may also be a person whose sex assignment does not align with their gender identity, In Old English, wīfmann meant "female human", whereas wēr meant "male human".
The big factor that limits sexual activity is a man's health, not a woman's.
All sex surveys based on self reports are bedevilled by the accuracy of measurement.
Men tend to marry women younger than themselves and die sooner; more women are widowed and thus lack a partner with whom to have sex.
Men can therefore look forward to longer active sex lives than women, though women seem unperturbed by it.
The term woman is usually reserved for an adult, with the term girl being the usual term for a female child or adolescent.
The term woman is also sometimes used to identify a female human, regardless of age, as in phrases such as "women's rights".
