It’s not a dumb question..
But I can’t answer it. It’s something I’ve always felt ever since I can remember. I wet the bed until I was about 7 years old, and for that I wore diapers. Maybe my private area was accidentally pleasured or stimulated by this and my mind connected the diaper with sexual pleasure. It’s no lie that some of my most intense orgasms have been while I was wearing a diaper. I feel ashamed by this and maybe it’s one of the reasons why I cannot keep a romantic relationship with someone, but I think my desire to get off in diapers is so deeply rooted in me that this is something which I cannot fight.
