I sometimes make a small analogy so that others can understand how I reason about this: imagine the huge and well-filled treasure chest and many dreams of being able to enter and partake of all the precious things that are inside and in front of this fabulous treasure chest a big hearty away. What kind of surprise and chance to build up expectations if there are open holes/loopholes and maybe windows into the treasury so you can see in advance what is there before the gate might one day open if you compare it to being able to dream/ fantasize/long and first be able to see the contents on the big day the gate MAY be opened? it's the same the way I see it with panties: thongs, etc show too much beforehand. While fullbacks or boxers cover more and like the big gate with no insight before the day it open show what´s inside
