1. Your Libido May Decrease
Again, this age-related change is more common in women and is heavily associated with hormonal changes around perimenopause. Another reason you may experience a decrease in libido is the mounting stress that tends to build up around the age of forty. You are no longer young and dumb and have to consider things that you may not have realized before. Alternatively, maybe you just have so many responsibilities now that you did not once have that you just lose interest. Stress management can help here and many other age-related health conditions that tend to set in around the age of 40.
