I was potty trained around age 2, and my first memory of trying diapers again was taking some of my youngest brother's cloth diapers and plastic pants when I was 5 or 6. I would put one on and wet it, then drop it in the diaper pail in our bathroom. We would occasionally have early 70s era Pampers if we were traveling, and those were so much better. I loved the smell and crinkle of the plastic, but it was a rare occasion have those around. He was potty trained the summer I was 6 1/2, and my diaper source dried up, so to speak. I still found the occasional diaper at relatives houses or in the church nursery/preschool that we had the run of as kids ( father was a pastor) up until my early teens when indulging my DL interests went dormant for a decade or more, although I still was very interested in diapers and accidents. I just didn’t wear myself.
After I finished grad school in my late 20s, I had my own place without roommates, and I rediscovered my DL interest online (Alt.sex.fetish.diapers, anyone?). For the first time, I realized I wasn’t the only one. I still only bought diapers occasionally and enjoyed them by myself, but it was enough to satisfy my DL urges. I wear more now and my partner knows of my interest and is supportive but not into it herself. I wear usually at home and typically a handful of times a month. That’s enough for me and I have no desire to try 24/7.
