They say we don't need our appendix, but people don't go around getting their appendixes removed routinely just because they might get appendicitis, now do they? If a person is clean, they'll wash there like anywhere else on their body that could harbor odor after a period of not washing. Vagina's produce smegma, and they can smell too if not washed, but we don't go around chopping off bits of labia. I'm not saying a person shouldn't do it if they so wish, but that people need to stop automatically circumcising their sons based on the "I wan't him to look like daddy," "He'll be teased in the locker room," and "It looks better" reasons.
