there is a definite 'left-pattern', because all men by nature have one testicle that hangs a bit lower than the other, and therefore causes the cock to sway more that way ... and pardon the obvious pun here, considering the topic, but 'nature abhors a vacuum' LOL ... anyway, its seems were talking more about how one is 'hanging', as opposed to how ones bulge looks in ones pants ... myself i have no huge bulge per se, more like a cock-silhouette, when freeballing or in loose-fitting boxers, but in tighter fitting boxer briefs, and in jeans, there is a definite big bulge ... even in regular boxers, if wearing a suit for example, i can plainly see the outline of my cock, including the head, thru the fabric ... guys who wear regular briefs or tanga-type (european-cut) briefs, would show more of a bulge ... if you doubt me and are well endowed in both cock and ballsize, just try stuffing your equipment into a pair of speedos or any other type of snug-cut and fitting bathing suit, and you too will have a huge bulge ! one of the very reasons for myself discontinuing wearing tighty-whiteys or regular briefs was an uncomfortable feeling of having to stuff it all into a smaller space, especially as you get older (im 41), and the equipment heads more south as the years pass, hence the greater comfort of free-balling or loose-fitting boxers that let everything hand nicely as nature intended ...
