Tickle Dates
So I came across a couple of sites (not apps per se) more geared towards the fetish community. One is called "FetishAlt" which I think has many fetish categories, and another is called "Tickle Dates." The only problem is I think these are paid sites, and I don't necessarily trust them with financial information. I could be very wrong though, and maybe they are secure. You can definitely create a profile, but I think you have to pay to see messages and such. If there are free ones I would love to know. With the increasing popularity of online dating, there is bound to be more fetish sites and apps to come.
