I definitely suffer from some ED. Getting hard is easier than staying hard. Cialis or Viagra make things work fine, and cock rings help a lot if I don't feel like taking meds.
Thanks for the kind words. The negative comments from some I take with a grain of salt, and consider the source and motivation.
I've read some medical books, news and articles on the Internet, a simple physiological phenomena can be seen as a symbol which determines if a guy's sexual health is good or not: morning wood. Scientists only figured it out morning woods has something to do with the hormone during sleeping, and they are still not quite sure how or why to cause such interesting phenomena. But they have proved that if a guy didn't get them for a certain period, it might imply that he already had some health problem to stop him from getting them. Sometimes it might be serious unknown disease, or some dysfunction of important organs which influence in the course of erection. But for most of time, a sudden decreasing of morning woods is simply caused by a unhealthy lifestyle, such as, smoking, drinking, lack of sleeping, too much pressure or an upside-down physiological clock. Age also affects a lot when it comes to getting morning woods. Actually, the frequency of getting erection will decrease once reaching 30, but with proper and regular exercise, paying more attention to eating, recommended sleeping of time and without too much pressure, a guy can still stay a healthy sex life even when older. About two years ago, my lifestyle was in a total disorder because some family members were sick and stayed in the hospital. By that time, I almost have zero wood in the morning, and I barely had erection in that time due to the pressure and lack of sleeping. When things finally settled down, all things went to normal, my morning woods and regular erection came back as well.
To sum up, if a guy has a proper lifestyle, he shouldn't have any trouble getting and staying hard, so if he finds it difficult to have and stay erect out of sudden, and without any obvious reasons like what I've mentioned previously, he might turn to professional for deeper examinations.
But I'm still feeling happy to hear that you can get erection! Trust me! Not so many men can when in your age!
