Is it normal to be insecure about how i piss/wipe my ass?

I've had this weird phobia that I piss or shit different then other people lmfao, it's so fuvking weird to talk about but legit I've been thinking about it for years. Basically since I was 16, I'm 23 now.

I piss in public bathrooms all the time and I admit to peeking at a friend every now and then, and yeah im doing everything the exact same, but I feel like something's off. And I feel like I wipe my ass different than other people. I get clean, it's all good there, but I don't know how these broads in the commercials act like they use three sheets that's some bs. I swear I'm doing everything the same but still I'm like wtf how do I know I'm doing everything normal.

I've literally asked a buddy of mine if I could straight up watch him pee because it's been bothering me for so long. Like not that I'm confused about the actual act of pissing cause I can't really screw that up, it's the whole handling it thing. Like how someone gets ready to piss and what they do during and after.

I'm not trying to hear how y'all do ya business I just want to know if anybody feels the same cause it's so pressing
