Well I knew it wouldn't take too long before I saw this here. This has been a hot topic on abdl websites, and it primarily centers around what each person feels the definition for a fetish should be versus what it actually does mean.
Per its literal and most commonly used definition, a fetish is sexual in nature.
https://en.wikipedia.org/wiki/Fetishhttp://www.urbandictionary.com/define.php?term=fetishhttp://www.oxforddictionaries.com/defin ... ish/fetish (note; any words primary common listing is always the first)
Note that while wiki and urgan dictionary are not considered accurate by "experts", they are both written and constantly updated by the majority of common people. Ask anyone on the street or look at any news article that included an adult in a diaper (or better yet don't), and they will also most likely include sexuality in their own definition too.
HOWEVER; there are also definitions out there that indicate this is not necessarily accepted by everyone.
https://www.vocabulary.com/dictionary/fetishhttp://www.merriam-webster.com/dictionary/fetishhttp://www.thefreedictionary.com/fetishNote many references like this also like to say a fetish primarily refers to magic worship. I'm certain we can eliminate these sources as being a little out of date though (lol). Also, there is a language gap in between commonly accepted words between the US (and admitably most other countries) & the UK (with also mixed views in a couple more European countries)
I have extensively researched, and found more than enough supporting evidence that -generally speaking- when someone does not differentiate between sexual and non-sexual fetishes, what they are saying will most likely be interpreted by others as a default- sexual in nature kind of fetish. (even if that is not what they really mean).
So, with this in mind.... I absolutely do not have a diaper fetish! I do however, have a strong will or desire for them. I have even found this to be true for most every single abdl as well- with only a very few exceptions. Oddly though, many dl's will vehemently deny they are not sexually attracted to diapers while also saying they have been inexplicably attracted to them since even before puberty- and therefore could not possibly have sexual desires in the first place- yet again swear to having a fetish (odd....). This makes no more sense than saying you have a person-fetish simply because you love your spouse (and yes this is even with the sexual benefits that come with a spouse). Love and compulsion is not a fetish! Get this straight people! Now, opposite to this, most ab's will agree with this same conclusion since they more align with the desires of a real baby and therefore do not have sexuality in mind any more than a real baby would.
Simply put, the great majority of anyone who likes or is compelled towards loving diapers does not have a fetish- especially abdl's. Regardless though, I do also like how the abdl themed diapers look, and am even willing to pay a little more for an abdl diaper that would work just as good as a plain one. However, the key point for me here is the old "form follows function". I absolutely will not buy an abdl a diaper like baminos, fabines, snuggies (now tykables), etc. This is because they all use the same no-lower-tape design, that when sized properly will not work properly, and will leak around their leg bands long before reaching any kind of capacity. Additionally, there are no other properly designed adult diapers (with a lower tape and proper fit) that also have an abdl theme. As such, I prefer- but will not buy- any abdl diaper currently available, even being genuinely incontinent first and foremost.
