Not saying specfically to you fire, just more in general -
I'm not sure the whole "they hate it because they had a bad experience" thing is so wise. It's right up there with "she isn't ticklish because the right tickler hasn't done it". There seems to be a bunch of guys out there who can't just accept that not all people like tickling or are ticklish. If they say they don't like being tickled or after a bit of testing obviously aren't ticklish it's best to just leave it and not try to force it upon anyone, lest you ruin a friendship, date or what ever. Good call from the starter of this thread on this date then, wasn't going anywhere and you handled it well.
