Everyone seems to be assuming that kids have exactly zero sexual feelings before puberty. At least in my case, this certainly isn't true.
I convinced my mom to diaper me a couple of times around age 5 and it definitely felt good "down there" even though it obviously didn't have the full context of adult sexuality.
I also have distinct memories of getting something resembling 'aroused' thinking about diapers and other things that now turn me on.
Then I kept having diaper desires off and on growing up but it didn't really hit me with full strength until puberty.
First, the very first time I masturbated and had an ejaculation I recall thinking 'this would be so much nicer with diapers instead'.
At this point I had no idea there was such a thing as a diaper fetish. I didn't exactly feel bad about it, but I had known for long that this was something to better not talk about and keep hidden.
Then somewhat later I kept having these recurring dreams related to diapers. After a couple of them, I entered "diapers" into a search engine which eventually led to DPF.
And the rest is history - I bought a pack of the largest size Pampers, and after some initial confusion because diapers were now quite different from what I remembered, I was in heaven.
Would I have ended up actually buying diapers without the Internet? Certainly, but it would have been later. I distinctly recall thinking a lot growing up that the first thing I would do when I was an adult and had my own place would be to buy a lot of diapers. DPF et al. just pushed me into doing it earlier, and perhaps also into actually using them both ways, but I would probably have started doing so sooner or later as well.
By the way, regarding kids sexuality, I can't exactly be the only one having some sort of sexuality at an early age. When I was around 8-9 me and some others were very interested in porno mags and even had "sex" with each other… I guess that's what Cultural Marxism does to kids?
But if you're around babies and toddlers you see them playing with themselves all the time, so it can't all be (((their))) fault.
