I was amused to see recently that not only did a bit of a tickle porn fetish business appear in Riverdale on Netflix as part of a side plot (I read about it here 1st) but the fan forums for the show are pretty much puzzled by it, or don’t like it at all (a rapist gets tickled on video w/o consent while he’s drugged; Kevin is the main gay character & folks are bemoaning that this is his big plot.) So innocent, they are...
Even though I’ve seen more puzzlement or complaining about it than anything else (“This is a fetish, I guess?” “But aren’t the characters under 18?” etc.), a few folks have picked up that it’s a nod to the Tickled documentary.
I have no doubt that brought /M tickling further into the mainstream consciousness - so much so that a mainstream show features it (M/M & F/M), which will likely propel it even further into fetish videos & the bedroom play of many.
