I think there are far too many self-proclaimed "experts" who think they know when someone is faking when they really don't.
I agree with you 100%. I constantly read threads in which people comment about the ticklishness of a given model, or what signs indicate that a model is ticklish or not. Frankly, a lot of them are quite wrong. I've seen many genuinely ticklish models react in ways that these so-called "experts" judge to be fake. I agree with Bohemianne that some "experts" are unfair because they accuse truly ticklish models (and by the same token, producers) of faking, damaging their reputation for no good reason.
It seems to me that many people have a very limited view of what ticklish reactions really are. They have one or two types in mind, possibly because it's how some people they personally know react and, as Rhiannon suggested, anything that's different must be fake to them. How can they think of themselves as knowledgeable when they clearly don't have the practical experience required to make such calls? To tell the truth, even people who have witnessed a wide variety of reactions can be fooled one way or another.
Anyway, because of this, most opinions about ticklishness have become irrelevant to me. Unless the reactions are painfully obviously faked, I give the model the benefit of the doubt, or at least I don't go and blast her on the forums. I simply don't trust all those little signs that are supposedly so telling. It's like ticklishscribe's comment in this thread:
For me if it's repetitive, that being you hear exactly the same laugh even five or so minutes later and for the length of the video, then in my view she's faking.
While it's quite possible that a model who reacts that way is indeed faking, I've personally seen a number of models I know first-hand to be genuinely ticklish react the exact same way. I mean no offense to ticklishscribe, to be fair it's actually not a bad observation, but it's the generalization that bothers me. I wish people would at least acknowledge that there are always exceptions.
Something that's really sad is that I've actually turned down a few models that I knew were truly ticklish just because I felt that their rather unique reactions would somehow be judged fake by the "experts". It's really disappointing when I have to do that, both for myself and the model. As if having to turn down a bunch of enthusiastic candidates who simply aren't sufficiently ticklish wasn't enough.
