[etch]

Do u guys have similar problem? I noticed that over the years esp recently my erection is not as hard as it used to be. Even fully erected, i can feel as if i just 90% of what it used to be. I dont think its age factor since im only 29? i also get tired easily which maybe related to that? On top of that, i gained slight weight, my height is around 1.72m & my weight is around 67kg. hardly fat i know.. but i was just wondering what could result in this. DO i need to see doctor?
