well if it were secret nothing would change since we wouldn't know about our secret penis

Men would magically touch dicks with themselves and women would penetrate their crevices unexpectedly. The surprise of a secret penis would add a whole new element to orgasms and make them more mysterious and anticipating to experience.

It would be like The Crying Game, only sexier.

They would be having fun with themselves and they wouldn't even know it.

If everyone had a secret penis, the world would be a much better place. There would be no wars because everyone would be dedicating their time to finding their secret penises instead of killing eachother.
