TIFU by trying to nair my b-hole with bikini nair

So I (27F) am going to an event where clothes can be removed, for starters I’m an incredibly hairy woman twins of Sasquatch. I hate my body hair and laser removal won’t work it always comes back and waxing is way out of budget, so there I was butthole in the air getting nair bikini applied when I felt a burn equal to 1000 suns and an Agni Kai combined (iykyk) and so we immediately tried to remove it and I jumped in the shower and tried to cool it down with cold water. I tried to scrub as gently and as quickly as possible. I’ve never felt pain this bad and I’ve given birth, broken bones, cancer, and have had 2 emergency surgeries for organ failure.
I now have a slight chemical burn on my asshole. Just wanted to share this with anyone who needs a laugh today and who needs to just relax.
TLDR: bikini nair is not for your asshole. It’s for the bikini area and no it doesn’t mean where the bikini covers.
