I hate the way deodorant smells, and I know that may sound oxymoronic, but I guess that's false advertising for you. I've met plenty of clean, well-groomed men, really classy fellas, who stunk to me because they wore deodorant. No insult on them, I just don't personally like it.

I make an effort to use the appropriate amount of soap so as to cultivate inoffensive bacteria in my sweaty areas while killing off the stinky ones. The mammalian body is designed to be an ecosystem for bacteria. Scientists have raised germ-free mice in labs by keeping them away from other mice and feeding them formula instead of milk, and that's not natural. When they're introduced to other mice, they catch whatever those mice have. Some mice have nice germs, some nice have nasty ones. There are no mice outside of labs who have no germs.

Most people use too much soap and basically nuke their privates every day. Then they act shocked when the stinky bacteria recolonise that free real estate faster than the nice ones. So they nuke again, and the whole cycle starts anew. Water and friction are enough for everyday, and use soap every couple of days or when things get nasty. Not too much, just enough to restore the equilibrium. Do that, and you won't be getting foul enough on a daily basis to need deodorant.
