L-arginine is a supplement that will probably fix you right up. You should read about it. If you decide to try it, get a good quality one. You can check Amazon and get a highly rated one.
So apparently I seem to have lost my interest in sex as well even with my testosterone levels being normal. I haven't felt any type arousal in awhile even if I decide to look at porn. Is there anything I can do for that?
Since you are waking up with erections, and your blood tests came out normal, physically there is no problem. Instead of rolling the issue over in your mind, it may be best to give it a rest now and let Nature take its course. Avoid porn and masturbation, and only enter into sexual activity when you have the urge.
From my point of view, I don't recommend prescription drugs nor supplements for your situation at this time. Once you start with those, will the body heal on its own or continue to have to rely on meds? Enjoy dating, and since your sex drive is at a lower level, put sexual interaction on the back burner for now. Plan ahead whether you deem it necessary to mention your ED and your past stress to your date when the time comes. I think once your sex drive normalizes, your body will properly respond.
