Just a thought I had
I got into thumbsucking because I needed stress relief, not because I had a desire to act or feel like a baby. The same goes for pacifiers. As a thumbsucker, I was curious about what they felt like. I pretty much see myself as just a thumb/paci addict who just happens to have a diaper kink as well, and that's why i'm here.
Did anybody else get into thumbsucking/pacifiers this way, or was it a direct result of your being ab?
