Things have certainly changed since "My Time" (and, now I'm sounding like an "Old Guy", since I've not been able to avoid becoming one  
   ](*,)](/images/smilies/bang.gif)
  ) when ALL Guys were EXPECTED to get Naked around all Other Guys, and LEARN to be Comfortable about it.  
The "trick" (no pun intended) was to not APPEAR to be scoping out all the dicks around, when that was precisely what EVERYONE was doing!  
The possible threat of what Might happen, IF you popped a Boner, was enough to keep you Soft!  
 
Since it wasn't supposed to be any "Big Deal", a Big part of "The Deal" was not getting BIG!  
SO ... we all Learned to "behave" accordingly, not be Obvious about dropping our eyes "below the belt", and carrying on as if it was all quite Normal!  
I guess my point is, the very thought of the Necessity to not get aroused was enough to make sure that didn't happen.  
In other words, the very Fear that you speak of will make sure you'll be just Fine!  Don't let that put you off, butt rather Embrace it, and "Just DO It"!  
  
Of course ... No Matter What ...
Keep Smilin'!!
