Sebastians think that they are awesome, whether they are or not. Some Sebastians are just obnoxious, while others have actual potential. Though Sebastians are generally good-looking, the mean ones will be horrible and crotchety in their old age, and as the years go by their penises will get smaller and smaller until approximately the size of a pea. This all depends on the niceness of your Sebastian. If he isn't a douche-bag, his penis may get even larger over time. Pick your Sebastian wisely!
Whao, that Sebastian is hot, but his penis is smaller than a thumbtack!
