I have a question: why does bulge slider matter at all, when you're going to be wearing armored pieces, pants, robes, and the like that will completely cover it up? That's only going to matter if your male character will be in his underwear 99% of the time. You could argue the same with butts, but at least your character's shape will still be defined, regardless of the equipment. I've also never understood how bulge size = breast size. Breasts are not reproductive organs, nor have the same functions.
