Yes i had, both family and friends.
And what i reacted dependes on my age and self awareness. Back when i was a kid i would try to give it all, prollong it all by all means possible. It was just pure fun and i was not thinking on stuff like fetishes or whatever.
When i got into teenager, i kept seing this around me but now i was too shy to go for it. Even lost some great oportunities because i was simply afraid of being different, of liking it too much. Dont know.....it got even worst when i finally found out that it could get sexual with the right person. Then i was scared and would cut any event. Altough funny enough i would still kind of instigate those events but then cut them short. I think it was still the mindset i had learned as a kid kicking in but then getting checked.
Then when i went past my twenties (not that long ago), i finally got a lot more confident about it and sorted out my feellings and the way i deal with this. So its back to "give hem all, dyeeee" or "kill me if you can". And its a lot of good fun mind you!
Actually these days i think the one and only place where i´m still really tickling shy is when i´m with people from around this Forum. Because i know how once i was a bit disturbed about it and i respect that people do not feel confortable to play with everyone. So my rulle tends to be, only play when 100% sure.
Out there in real life....i´m quite more adventurous about it these days....but it comes together with all my life also. All these "stands" about tickling could relate and make total sense together with other personality traits and stuff i was going through at the time.
Today im pretty much conffident i´m "the one" 😀 so i do whatever i feel i can do and just enjoy it and take it playfully. Be it familly or friends!!!
Almost all of my female friends know that i have this trend of instigatting tickle fights. its well known. No one has a problem, those who dont like it just say they dont like and i dont pick with them. I usually ask if its ok after the 1st time i tickle some female friend 😀 And from there its game on or not.
Generally im really loyal when in relationships. Never felt that tickling was in anyways a betrayal....yeah, it can become a turn on, but then again, so can me seing a friend in mini-skirt.......and what???? i dont walk blindfolded because of that, i should not stop enjoying tickle fights because of that either. I know i will not have sex with some people, not really, its simply not a possibility.
Hope this answers
HAVE YOU EVER HAD FRIEND OR COUSIN THAT TRIED TO..playfully pick a tickle fight with you M or F,..not knowing you were into tickling 
and in retaliation did you go over board and try to give that person the "TICKLERS ALL"or did you keep it on the low low,..give back as much as was given,..
, did you try to provoke and prolong the tickling being administered or again keep kinda low key?
Sorry for the obnoxious rhyming.
