Good question. I'd say they maybe would say that it's liddle bit sexual for them... cuz if it wouldn't I guess they wouldn't care at all... ...!?!
Or, maybe they're creeped out by the fact that some anonymous person asked them for personal information, possibly lied about why they wanted it, and then posted that personal information on a sexual fetish forum so that other posters could masturbate over it.
That'd squick me out a little bit, and I'm not even a woman.
I'm also a little interested in the fact that this thread is more about what can happen to the OP "legally", that is to say "can I be forced to not do something that makes people uncomfortable, which I would otherwise do whether they liked it or not?"
I've said for a long time that this community breeds a culture of "just how much can I get away with?", and this is a perfect example. It's not about whether or not the OP made the celebrity in question uncomfortable, or lied to them, it's whether or not they can get caught.
Now, as to my own personal views on the "ethics" of the situation, I think that the entire practice of pestering celebrities about their ticklishness so that we can use it as jerkoff material, and the cataloging of same in a subforum on this site, is creepy and stalkerish, and I've said that multiple times in the past. Granted, it's not going to go away, so the least we can do is not be sneaky about it and lie to these people so that they tell us what we want to know.
But, yeah. Good luck with THAT.
