She walked into my room when I was age 15 and found diapers... I was so embarrassed, but she didn't care.
I told her about my fetish a few weeks later. She was understanding and said, "Everybody likes their own thing"
She reminds me to dispose of my dirty diapers in a subtle way... so embarrassing, but she just likes a clean bedroom (understandable)
Age 22, last week I order some diapers from the internet. I forgot about them. Today, as casual as possible, "I think you ordered these free samples" and handed me a pack of diapers. I was hardly even embarrassed. She then started talking about how our faucet was leaking. Goes to show you where her emotional priorities are.
Thank goodness I have a Mother who understands the fetish and could truly care less. If my Mom wasn't as open, I'd probably have some psychological problems later in life.
