Later in life (50+) a considerable number of both men and women find that their interest and desire to have sex, and ability to function, becomes much less.
In women the most common symptoms are a lack of desire or interest, a lack of arousal and lubrication, difficulty having orgasms and pain associated with sex. The medical term for this is female sexual dysfunction (FSD).
In men the common symptoms are a lack of interest and desire and difficulty getting and maintaining an erection and achieving orgasm, as well as a loss of drive sometimes manifesting as depression. The lack of ability to maintain an erection makes this issue more obvious for men and emphasizes that the problem is in the body, not just ‘in the mind’. One of the best early indicators that something is not right is the gradual loss of early morning erections.
