There is a big space between, "an app just for ticklers," and, "I don't want to put tickling in my bio on traditional apps." I'm going to rant for a minute, because this is a TMF thing that gets under my skin a little.
I know this gets said a lot, but hear me out:
1) Tickling is an easy fetish to sell to a vanilla human
2) Most people are ticklish, to some degree
3) Connections should be about more than your kink
Of *course* you shouldn't put tickling in your bio. You probably shouldn't put down how often you masturbate, your views on oral sex, or how open you are to getting pegged...
Because that would be weird and anti-social, right?
Case Study: I've dated eleven women in the last two years, most made it to the bedroom, and three had staying power. Out of that pool, ten were open to being tickled in the context of a relationship. Eight were open to being tickled while tied up. Five legitimately began to get off on it themselves. For reference, I am of 5/10 in terms of looks and charm.
"But what I really want is a hookup, one-night thing."
Again, the options are there - and we don't need a tickling app to make them work. Swinger parties. Fetish parties. Fetlife. OKCupid. These tailor to same-day intimacy with limited follow-up expectations. Be direct and clear about what you want and what you can provide that they want, and roll the dice.
The *big* problem seems to be that a certain subset of ticklers want to put the kink before the human. Making access to a tickling partner the singular goal of interaction makes that other person two-dimensional: they are just skin and a pulse to actualize a fantasy that has nothing to do with them. And they can. Absolutely. Tell. It's no different than the guy who heads to the bar saying, "I need to fuck something, anything."
(Note: not shaming anyone for having those feelings/thoughts. The odds are just stacked against you in that paradigm.)
We set up a lot of false dichotomies on TMF.
"Should I tell her about my kink on my first text, or take my secret to my grave?"
"If I tell her about my tickling kink, will she immediately tie herself up for me and let me do anything I want to her, or will she laugh at me and tell everyone I know and get me fired from my job?"
Can we just... not? Can we, maybe... treat tickling as a slightly-outside-normal, largely harmless turn-on that is a facet of who we are and not our *entire identities*?
