That all depends on how, and the context in which it’s done. My first girlfriend would spend hours tickling my back in between sessions - I never forgot those sunny days.
Now with more aggressive tickling - it is akin to a violent attack, and my father used to tickle me until I couldn’t stand it, and then push some more. Often it ended with me in tears… so with my son, sometimes I’ll grab a foot and start tickling it like mad - but I have a MUCH shorter cutoff time so that it ends with him laughing.
So it’s not simple - but consent is a huge issue.
For sure, as a teenager -
