This is a little embarrassing for me to admit, especially in a public forum such as this, but there seems to be no judgement here, so I'll just come out and say it:
I love wearing diapers.
I started wearing them when I was 15 years old and, at first, it felt both weird and exhilarating when I had them on. Weird because I was, you know, a 15 year old wearing diapers and exhilarating because I was a 15 year old wearing diapers. Just knowing I was wearing something I wasn't supposed to be wearing was so thrilling and exciting to me. As I kept wearing them (in secret and in the privacy of my own room), the feelings I had while I had on a pair of diapers evolved from 'this feels weird, exciting, and kind of naughty' to 'this feels normal, comfortable, and right').
Anyways, fast forward to nowadays and I'm not lying or exaggerating when I say I'm 100% more comfortable wearing diapers than I am wearing 'adult' underwear. I don't think there's really a sexual nature to it for me, but I won't deny getting excited at times when I feel my diaper just to affirm to myself that 'Yes, I'm wearing a diaper. I'm wearing a super soft and comfortable diaper right now.'
Unfortunately, since I live with someone else (my grandpa, who obviously doesn't know about my love for diapers), this means that, even now, most of my diaper-wearing is done in secret and in my bedroom. Whenever he goes up to our summer home for a few months during the summer are the only times I can wear my diapers all around the house and not have to get worried about being caught. Hell, last summer I even went out for a walk while in diapers. First time I'd been in diapers outside my home since I was 15 (I wore during my last day of school that year).
I genuinely want to be diapered 24/7.
Also have a bit of an attachment to the adult baby side of things too. But for me, it's less 'I want to dress, act, and be treated like I'm a baby by a mommy' and more 'I have a baby bottle (that has an alternate lid that lets it also serve as a sippy cup) that I like to use when drinking milk, I sometimes like to buy and eat baby food, I find some baby/toddler toys attractive and think about buying them for myself, and I sometimes imagine what'd it be like if I were to convert the spare room in the house into an adult-sized nursery'.
