I Have Had A Cough Since The First Week Of

I have had a cough since the first week of June. It has not gotten worse, and it's really not all that bad, but it is annoying. i still regularly work out and go to work and live life normally. I am a male and 45 years old. i have consulted my dr. and have done my best to explain to him what's going on. He said, men cough. This is different than anything I have ever experienced. I'm not worried, but should I be?
