A girlfriend in high school found my stash of diapers, plastic panties, baby lotion, and baby powder and asked me if they were for me.
I remember being pretty scared when she confronted me about it thinking maybe she would spread it around that I wore diapers.
I told her yes the diapers were for me, and at first she was pretty quiet about it. Then she asked me why. I told her I liked to wear them, and that I always liked wearing them because they felt good and turned me on.
Instead of freaking out about it, she had me get undressed, and proceeded to diaper me.
The diapers I had at the time were Pampers size 6, and didn't really fit me too well, but I could still wear Gerber toddler size plastic panties even though they were a tight fit.
She rubbed me off through my diaper and plastic panties saying that I was her baby while I sucked her titties.
We did the diaper thing off and on and had vanilla sex too, and were together for about a year.
