I never got to stay at friends houses or have them stay at mine because I didn't stop wetting the bed until I was 17
Why do you still think about that?
I still haven't figured out, but it might be painful memories.
I'm sorry you had to go through that. You should put it behind you now though, rather than keep thinking about it. You can spend nights at friends houses now that that's no longer a problem, going forward
I'm into regressive behavior / Freudian psychology and it has made me think about it.
It is best to overcome your fear by doing what you were hesitant to do.   Your know;edge will help you better understand yourself as you do so.
