That's ..... A good question.
I'm a female - but also a ticklephile, so I'm a tad bias...
Personaly, I'd see it as really cute and sexy <3
Sadly, most people don't think tickling as sexy.
But... Ticklish guys, who actually liked it ? 😉 heheh, yeah I think that's soo hott!
I've never dated a guy who liked being tickled, they all loved tickling me - but whenever I'd do it back, they never liked it.
As far as I can tell, my past boyfriend all thought it was cute / sexy how I liked being tickled,
So I imagine "vanillia" women would think the same thing about ticklish guys.
Idk for sure, as I said - I'm a little bias (having a tickle fetish myself) 🙂 hehe
