Is it normal that i love tickles in a non-sexual way?

I've been debating this with myself since the past 3 years. i mean, i know that tickling fetish exists, but i don't feel aroused or turned on with tickling. i feel... happy. like, rather comforted when i think about getting tickled or tickling a friend or my gf. it makes me feel a wave of serotonin that i cannot comprehend yet.

I also do art. and like the mayority of it is about tickles. a character tickling the other, like a tickle fight. if they're a couple, then they cuddle and snuggle and tickle each other and that kind os stuff

Just the thoughts about getting all comfy and snuggly with a comfort character or my gf, and then it all turns out into a tickly mess it makes me go silly.

But there's a thing i don't get. because if the one tickling me is a member of my family, i don't like it. i feel uncomfortable and rather awkward about it.

I remember that when i saw a tickle scene in a cartoon on tv, it gave me second hand embarassment. but if i saw it alone like years later it gave me that same serotonin wave i said.

Is it normal? (」ﾟﾛﾟ)｣
