You're right, Nobody Special, the whole thing about size is just STUPID! A dumb guy with a oversized dick is just as useless as a bimbo with oversized tits.

Second thoughts. Probably less useful; at least the bimbo doesn't hide her rack away completely and we can enjoy the sight as long as we don't have to talk to her. A big dick might be interesting if he could wave it around in public, but Thank God that's not common.
