Hi, I'm 43 year old male, no heath problems other than allergies , I have been having problems with a weak libido and soft erection, I get morning erections with know problem, my Dr. has giving me Cilias ,It work but I have to a small amount because it cause me to have a bad head ache. my problem is sex isn't always planned and at my age why am I having this problem, up to my late 30's I never had this problem and was always turned on just by the site of an attractive woman with out any problems. Could it be hormonal
