Now, don't get me wrong. This ad isn't sexism-free, what with the message that men should clean their junk so hot women will want to play with it, but the general absence of male hygiene ads contrasted with the sheer volume of such ads for women has helped to enforce the cultural notion that women are dirty and men don't really have to try.
Still, one funny "wash your balls" ad will never outweigh the decades of nauseating "freshness" messages we've endured.
