Eating out?

So I’m not a Virgin but I’ve never been eaten out, it’s not that I don’t want to but the opportunity has never appeared, no ones offered and I’ve never asked as I feel too weird doing it, if they wanted to they would’ve offered yk? Anyway I was talking about it with one of my friends and she said the experience was something she couldn’t describe, so I’m curious, can any of you guys describe what it feels like? And something other than fireworks and blah blah blah lol
