Nope. Not really.
All my HS buddies and I grew up in locker rooms, swimming pools, and on the nude beaches.
No one ever thought that you needed separation walls between urinals or that anything but the open showers made any sense.
Being naked with other guys was viewed as perfectly natural.
A dude would rip one in the locker room, and some dudes was crack up laughing, someone would say that this was disgusting, and the offender would almost invariably reply, "Now, it is disgusting, and when you were fucking me, this was fine, rite?" At that point, everyone else started cracking up until the next dude ripped one, too.
Later on in college, if it was an all male party, sleepover or whatever, no one would lock the bathroom door. So, you barged-in, and a dude was either pissing, or two or even three dudes were pissing in together, or a dude was taking a dump. Wow, no one cared, and no one commented. At times, guys were having sex in the corner of the bathroom, and no one made any remark about it. We were trying to grow up, and thought that any reaction to what was obviously going on was immature.
Some dudes made it a point of sharing the news about the quality AND the quantity of the dump they took with the rest of us in the lockers, bars or wherever it was males only. Everybody agreed that the dude was disgusting, and we all moved on to the next subject.
I believe that while growing up your curiosity extends to virtually everything, including the subjects you mentioned. Once, more or less everybody talked this thing thru and once everybody agreed that this was disgusting but natural, the curiosity was sated.
The thing that really mattered was that most of us grew up being comfortable while being naked around other guys, talking nonsense, watching other dudes do whatever they were doing at that time. So, a pretty strong bond was created, and hardly anyone felt excluded, isolated, underestimated, etc..
Basically, you got it out of your system at the right time and age.
