Should teens wear diapers

I wouldn't say should unless there is a medical reason. Now can teens wear diapers is the better question. If you or whoever you're talking about likes them then it is fine. When someone wears a diaper for personal desire they are usually fit into a group called TB/DL or Teen Baby/Diaper Lover. Teen Babies like to do baby things and/or they feel safe in diapers. A diaper lover is sexually attracted in some way to the diaper.
