One of my best friends I think is a diaper lover. He is always obsessed about incontinence, making jokes about people being incontionent. And one night, I notice tucked between his bed and wall were baby diapers. He said they were for his sisters upcoming baby adoption, but his sister hadn't even seen the baby yet so I imagine she didn't know the size. And the bag was open. And shortly after that, he put a lock on his closet door. If I get one more strong hint that he's a DL, should I maybe ease him into the concept?
