I'd need more details. I'm the type of person who can't just pretend like I can read your mind and construct a nebulous scenario of what you may or may not be imagining, to then give a knee-jerk answer of 'yes' or 'no'.
For instance...
-Breaks: Are they every 10 seconds..every 10 minutes...every hour? Do they last more or less than, say, 30 seconds?
-Restraint: Am I tied down (to what extent/position), or am I free to move around (like, getting chased around and pinned)?
-Intensity/Tools/Methods: Is it all light tickles (knismesis) from feathers and light fingernail tickles, or heavier tickles (gargalesis) from *digging into* ribs/armpits, getting heavier raking of fingernails? or more like 50/50? Are my feet gonna get oiled and hairbrushed? Might my underarms be getting 2 nonstop hours of fingernail tickle torture? *GULP*
-Spots: Is it one spot at once, multiple at once, are only my most ticklish spots getting it? Or are other not-as-ticklish areas getting teased as well?
-Lers: One or more? Are we friends or am I attracted to them? Are THEY attracted to ME? Are they truly a ler (or ler-leaning switch) tickle fetishist, or just a hired professional? Is their 'tickling style' cute/playful, sensual/spicy, coy/quasi-sadistic, very sadistic, etc? I will say, in my case, I'll only entertain the idea of female lers. I don't like male lers for myself.
By "could I", do you mean 'could I' endure it without dying, passing out, losing my sanity, yelling a safe word? Do I even *have* a safe word?
If I'm A) restrained optimally and getting heavy tickles on only my most ticklish spots, with relatively short and infrequent breaks, by a very skilled sadistic tickler fetishist, and have a safe-word, I would not be able to resist using it... sooner rather than later.
-If it's B) all the conditions of A) with the exception of lighter tickles vs heavier....eh, MAYBE. It'd sure be a lot of goosebumps and shivers and giggles!! But it's theoretically manageable. Especially if I'm attracted to the ler who has that quasi-sadistic/teasing nature *sighhh*

It'd be a massive turn-on, but still very hard to bear XD because I'm just really ticklish
😛 Don't tell nobawdy! lol
-If it's C) all the conditions of A) with the exception of having NO safe word...then, psssh, like it or not, I'm gettin' tickled for a day!

And I think I'd probably pass out.
There's just a lot of factors to consider, for me at least.
