You are certainly reaching a stage where most aged men faced,
low-sex drive, iropause or andropause. It involves the hormonal,
physiological, and chemical changes that occur in all men generally
between the ages of 40 and 55, though it can occur as early as 35
or as late as 65. These changes effect all aspects of a man's
life.
Some believe that male menopause is the road to oblivion, the end
of our sexual power. But for those who have the courage to take
that road, male menopause is the passage to the most passionate,
productive, and purposeful time of a man's life. What you actually
needs now is a good communication with your spouse. Be frank, age
is catch up on you. Dun act hero or suffer in silence.
