I am also experiencing weaker erections in the last 5-ish years. I never did lose my morning wood, that I noticed. I have it pretty much every morning. Now that I know its important I?ll have to start paying a bit more attention to it. I strongly agree with other replies. I think its time to stop living in the confines of your mind. Time to get your mind and hands busy with all sorts of healthy activities and hobbies.
When I was in my early 20s I battled a very serious bout with depression and anxiety attacks. During I would say 90% of my conscious waking hours sex was just totally not on my radar at all. No arousal, no erections, no nothing. In that 9-12 month period I only worked up enough courage to have one encounter and it was bad. REALLY BAD. Very weak erection. I was only 20! Previous to this episode of depression, I had been in a very healthy loving relationship with my first girl friend of 2 years and had NO issues becoming aroused or erect at all. Long story short. In this case at that chapter of my life porn hadn?t screwed me up yet. My general overall mental health was just having a field day keeping me from having any kind of gratifying sexual experiences. Even M+O had lost its appeal.
I?ve read some of your posts in other threads. Don?t give up man. Get out there, enjoy life and all its wonders. There comes a point where dwelling on a problem becomes worse then the problem... I have hope man. This is the most natural thing to humans. Yes we?ve fried our brains with some pretty potent junk. But 1000s of years of evoultion to natural sex is on our side. Stop thinking, start living. Nature is bound to take its course at some point.
