Hello, I'd like to help you with your question.
As long as you are not hurting anyone else, wearing diapers is fine to do. People often enjoy the sensation of wearing diapers because it takes them back to a time where they feel safe and cared for, as when they were an infant. And though there may be some issues stemming from that time in your life, if you do not feel distressed or have any symptoms bothering you in your daily life, then you can wear the diapers without worry.
I hope this has helped,
