I'm mildly curious to see where this conversation is going to go from here. I don't happen to share your fetish; I'm not a potential partner for you, sexually or otherwise; I don't see how stuff that you do (I presume) in the privacy of your own home affects me in any way; and I'm personally not much interested in discussing diaper fetishism (or any number of other subjects) in general terms; so (in my case at least) what's there for us to talk about?
I can imagine about three directions in which this conversation
could go, if it's to go anywhere: (1.) someone happens along who's either sufficiently interested in diaper fetishism to want to discuss it further, or sufficiently turned off by it that they can't resist sharing their reaction; (2.) someone gets interested in something else you've mentioned -- relationships, expensive hobbies, miniature dachshunds -- and we get to talking about that; or (3.) you get interested in what someone else is sharing, put your diaper fetish concerns on hold for a while, and join
that conversation. (Anything I missed?

)
That said, welcome to Psych Central!
