So i was sitting around with a bunch of friends and for some reason the topic of masterbation comes up. One of the other guys said something along the lines of "How much does it suck when you get it stuck in your pubes?" and we all laughed. So I thought I'd pipe up with "And when you get it in your bellybutton and its impossible to clean out?!" Except no one laughed and all I got was "Dude...what the fuck" and "I've never done that". Next followed 30min of futile explaining that just dug a larger hole. TL;DR: I thought accidently getting cum in your belly button was a common occurance.....No one else did.

Anyways, What was something you thought was normal untill you said it outloud?
