I have to over concentrate to urinate. any slight distraction shuts me down. once i start i'm fine but starting is the problem. no other penile probs?

Shy bladder: You have shy bladder. Work on relaxing, and you will find that it helps.

Social phobia: Social anxiety is an excessive fear of a social situation in which one has the perceived potential to be embarrassed or humiliated. Urination requires a synchronization between the sympathetic (flight/fight) and parasympathetic (rest/digest) nervous systems. If you fear you are being watched or need to "perform", you'll have an overly sympathetic response, preventing you from urinating.
