I think you can be right. You do not have to compare yourself with others, but only with yourself. So a little improvement is an improvement!
As I wrote in this forum, I asked one of my best friend to be my pee buddy, and he is not paruretic. Finding a non-paruretic pee buddy may be useful for you too. So you will face the situation with someone who has not the problem. As I repeat, consider your best male friends, and you may find that someone could really be helpful for you. There must be confidence and trust between you two. When I asked one of my best friend to become my pee buddy, he was very understanding, even if he's not at all paruretic. And he confessed me some other situations where he felt uncomfortable. So our friendship has increased. Very good experience. I know it can be difficult to tell one friend "Hey, I'm paruretic, would you like to be my pee buddy?". But probably at least one of your friend would be happy to help you. Try to describe him your situation, tell him you feel uncomfortable, that you would like to overcome your problem, and that he could be of help for you. If your friend really cares for you, he will be understanding and will probably accept. You have to underline that there is no need of "intimacy" between you. He does not have to see you peeing (I mean your genitals!) Just stand by you when you try. I advise you to try to pee together. You will feel "protected" by the presence of your close friend. At least, that was my experience.
