How's it hangin' ?

Oh these earth-shattering questions - which way should your toilet roll be positioned? With the loose end over the top and to the front, or underneath - close to the wall? I'm an under man myself - always seems to me that it's more sort of discrete that way - not so much in your face as it were, but it appears I am very much in the minority.  As I'm on my own, it doesn't really matter that much but I would hate to think that any visitors might be embarrassed or confused.  What do you think?
