I'm not quite sure how to take your question. Do you WANT to stink?
Some people just don't sweat as much as others. You may be one of what I would consider to be the lucky ones who don't need the extra help of deodorants.
Body odour is actually created by the bacteria on your skin breaking down the sweat secretions. The more frequently you wash, the less chance that bacteria has to grow. Even if you don't normally need to use deodorant, you can probably conjure up enough bacteria to make a stink just by not showering for a length of time. (If that's what you really want.)
