Is it normal to dig in my butt?

my friend had a medium body but she had a big butt her and I cracked Easter eggs on eachother's and some how confetti got in her butt, so she puts her finger down in her panties and touches her naked butt trying to get the confetti out, then she got some of it out and then when she smelled her hand and told me to smell it, so my stupid self listens and I smelled her hand after touching her butt, and her hand smelled like ass, NOT like shit, but like a smelly butt that stinks, we then went inside and went to my room she said she still had confetti in stuck between her butt so she closes my door and pulls her pants and panties down, I saw her big naked butt and I then she bent over and spread her butt open and she said" do you see any confetti around my butthole" I said yeah, she said " can you take it off" I said "I guess", so then I took all of it off, she said "thank you". I said " were you embarrassed that I saw your naked butt and your butthole", she said " a little bit but I wanted that confetti out from between my butt" I said "ok", she said " I hope my butt didn't smell bad when you took the confetti off because I didn't take a bath last night", I said " it smelled like cherries" ( I was lying) she said " stop lying my butt is smelly most of the time plus it is big" I said her butt didn't bother me" she said "ok", so then we went outside to talk, I would never forget that day I saw her big naked butt and her butthole.
