Yes, I have had size interactions in real life, but I was the one who initiated them, so I’m not sure if that still “counts.” 😁
I’ve romantically/flirtatiously roleplayed size stuff with more than one girl I was potentially interested in. I did it in a normie-friendly, playful way, not in a kinky-sounding way or in a way that would set off a normal person’s creep-o-meter. I never told them it was a kink or a special interest of mine or anything like that, because:
A) Why make it weird or awkward when it doesn’t need to be?
(Also, I wouldn’t want someone to feel pressured to play along, or to like something just because I like it.)
B) It’s an impossible fantasy anyway, with no chance of ever happening in real life, so why would they need to know?
When I did this roleplaying, there were a couple girls who got really, REALLY into it. They embraced being tiny and loved every second of it (and embraced the idea of staying tiny indefinitely). No, I don’t think they had a size kink, and I don’t think they were sexually turned on by the sizey stuff itself…I think they just really enjoyed the emotions (and the flirtation) that came with the fantasy. I think it’s a fantasy that speaks to something pretty universal in the female psyche, which is the same reason why Twilight and 50 Shades of Grey became so mega-popular. I never got a negative response from any of the girls I tried it on. Maybe a couple neutral responses, but most of the time, the responses were either positive or VERY positive.
