Oh crap! That one's good!
Well bubba - may I call you bubba? - basically sexual reproduction only evolved about a billion years ago, multicelled organisms evolved long before that. Sexual reproduction used to involve spawning, and a simultaneous mass release of eggs and sperm. This still occurs in many species, especially the relatively immobile ones like corals. Sexual reproduction had many advantages over asexual reproduction especially wrt to evolution and diversity. It was an advantage for a specific animal to ensure it's sperm fertilised an egg, and the easiest way to do this was to fertilise the egg pre release and various mechanisms were developed for this - a penis is just one of them. Selective mating greatly advanced biodiversity and enhanced the development of desirable traits. All of this was still hundreds of millions of years before placental mammals.

Some unicelular organisms use sexual reproduction
This is the best answer bubba can get :)

Uh, these had better be euphemisms, `cause I don`t know what bellybuttons have to do with this.

Yep, penises just randomly evolved without vaginas . Well done bubba, you have cracked the gay conspiracy.
