I am 47 male.Ihave lost my lust.My penis doesnt get stiff.?

I dont know if I have this prolem only with my wife. I havent tried with any other woman. last night when we wanted to have sex after tow months I just ejaculate in a second. After that the more I tried to make it stiff,the less I was successful. It didnt get stiff.Some mornings when I wakeup its that stiff that I make a hole on a wall. I have tried to masterbute in the bath, but it hasnt got stiff and I didnt have a sense of lust. I dont know what to do.

This sounds psychological to me. If your majic wand gets stiff enough to poke a hole in a wall, your issue isn't likely based on the physical. Almost everything you mention in your question leads me to believe your dealing with psychological issues. Contact a professional for help.
