Personally I think people would have a harder time digesting just wearing diapers to get off, as opposed to wearing diapers as an age play thing. I mean people already think the diaper part is weird but acceptable as part of people pretending to be a baby. Pure DLs would just come across as creepy and lead people to believe they get off to any diaper wether on an infant, the elderly, or anyone inbetween.
I mean no offence as I myself am mostly DL and when I got exposed people asked if every time I saw a diaper, diaper package, or comercials did I get turned on.
