Mom and dad are long gone now. But I'm pretty sure they knew. Nothing was ever said though. The first times were when I was probably 5 or so. I couldn't help sneaking a pair of my little sister's rubber pants into my bedroom and I'd put them on at night and enjoy them. I'd take them off and hide them under the dresser. They were always gone when I went looking for them. …so, I suspect Mom knew who had hidden them there.
I seemed to grow out of wanting to wear diapers and rubber pants then till when puberty started. All of a sudden baby pants and diapers came flooding back into my mind. Driving me crazy. About that time my little brother got put back in diapers for bed wetting. It only took a few days of diapers and the shame to “cure” him. But for me those rubber pants left in his drawer drove me crazy. I HAD to have them. One night I woke up early morning , sneaked over to his dresser and took them out. I was really too big for them but with some effort I could wear them. OH My GOD ! I was in heaven. I used them every night till they fell apart. Worried that Mom would see them torn up, I tried to sew them together. (Like she couldn't tell the sewing job of 13 year old kid on ripped to shreds rubber pants DUH). that's when they disappered…..
Those were the plastic pants that got me hooked. I still remember they were Playtex Toddler Extra Large baby pants. I wore them with a diaper one night to experience what it would be like to wet a diaper. What I experienced instead was a massive orgasm (my first ever). I ended up spending over an hour trying to wash out a giant cummy mess while trying to figure out what happened, so I wouldn't be found out. (Don't hide you washed diaper between the mattress and box spring either. It leaves a giant water stain for Mom to find and question you about).
I'd have to be a moron to think my parents didn't know something was up with me and diapers. That wasn't enough though. When I got old enough to buy plastic pants without them knowing, I got several pairs and hid them in my model airplane boxes. Nobody would look there right? BUSTED again…. Nothing said.
Many years later I would wear often when not at work with my loving wife's blessings. Even out in public under my clothes. One day while going to church with my wife and kids I suddenly felt a gentle pat on my bottom. Turning around there was Mom. Smiling….nothing said. Her trained eye evidently saw my diaper butt and wordlessly commented. So can I say they knew? Not in the classic sense of being outed. But yeah, they knew. But never said,. Mom did say to my wife once that I was “peculiar” though…..
