I'm 4" long by 5" when soft and 7" long by 5.5" when hard, I think my cock is probably average, maybe a little larger but I have big, low hung nuts and these are noticeable
When working and wearing a suit I like the freedom of shorts but I do end up with a noticeable bulge that sometimes is in the suit-leg of my trousers. If I wear briefs then everything is pulled upwards and then there is just a bulge in my trousers groin area.
I don't mind the bulge most of the time, however professionally when working it would be good to be able to disguise things a little.
I do like checking out other guys packages though, and wondering what is there is all part of the fun
