It's ladies and I'd probably die of boredom. Sorry, I'm not that ticklish to begin with. Plus for me it's not additive. If I'm tickled by two people, they sort of cancel each other out. I think many people are this way because when I tickle I get better responses when nobody else is "helping" me.
Honestly? Probably love it. I'm not incredibly ticklish and it's very, very rare I get that 'overload' feeling. Feeling the pull to make it stop a little stronger than usual would definitely be an experience. That being said, safeword would be an absolute must for that.
