I go by badbabyboy, and as you can probably tell by the name, discipline and a strict caregiver are a very important part of my kink. I grew up as a bedwetter, which clearly contributed to my sexual attraction to diapers and its link with shame, scolding, spanking, etc. (though don't get me wrong, my parents never punished me for wetting).
I identify as a switch, and though I'm more of a sub, I also top. If it involves someone peeing, being put in diapers, and/or getting a spanking, I'm in.
I am much more of a DL than an AB, though do get into a "naughty little boy" type headspace with pants wetting, pullups, etc. with the right lead up.
