Sweat doesn't stink. Sweat interacting with bacteria on your skin does. I shower, I change and get on the bike within a half hour. I ride in bike gear with a full change of clothing once I get to the office, quick wipe if I got terribly sweaty, air dry and/or dunk head in cold water to turn the thermostat down ... no stink as there is no bacteria on my skin. If I ride at lunch I'll shower afterwards.
