Let's distinguish. There's tickling, erotic tickling, and tickling with nudity (ie, "porno tickling).
I figured the post was about participating in, not media material. Erotic tickling is the only means by which I can say I really like being a lee. Doesn't mean "genital" tickling either. But light strokes gently all over the skin that feel very ticklish and puts you on the brink of a giggle but instead you just moan it out....that's really fun. It feels GOOD as well as ticklish.
Sure, there's too much "porno tickling" as mentioned, but that's not = erotic tickling. I didn't want the two to be confused. With that said, yeah it's not that often you see it in media (pics, etc).
But again, as far as participating goes, it's really good.
