I often use loose boxer shorts which is comfortable and allows my softie hang along the leg. Sometimes I use old fashioned Y-front underwear and put the cock through the hole and then let it hang along the leg. It gives a nice shape of the bulge and its easy to see the lines of the cock Try yourself... Well, ordinary boxershorts works too, they also gives an obvious bulge but the shape and lines of the cock is not as clear as when I let it hang along the leg. Anyway, I like when somebody whoever it is, look or stare at my bulge. Its also nice to see when somebody looks at my bulge when I use swimwear.
