I am 45 years old. Presently I have noticed weak erection during intercourse. This problem is since last 6 months. Earlier I did not have this problem at all.
so what has happened in the last six months, are you loosing interest in your spose? maybe work stress, or try to think of the simpsons "homer loves mindy" maybe there is a lady at work who you are subconconsioulsy interested in and it is affectig you at home.
