Anyone else think the human penis is an amazing piece of evolutionary machinery?

Should I get my penis bifurcated? Is it true that it increases sensitivity?

no, not compared to the eye or the brain, or our ability to sense and interpret sound waves.

No, it doesn't even have the penis bone or spines other mammals have. It's more like a failure.

that is part of what makes it awesome. Our penis is supported by compartments filled with blood, rather than needing a secondary support system such as a bone. I will agree that there are much cooler penises in the mammalian class (whales have prehensile penises), but that doesn't make our human penis any less amazing.

Does foreskin have a function, or is it just leftovers from a penis sheath?

Tapirs have the best penises. Go check them out on google.

Monkeys had spines. They must obviously not be necessary. Although nowadays with penises being so important I can imagine special features of the penis being a sign of status

Rhinos are pretty well endowed too. They have to penetrate a female rhino. I wouldn't be surprised if that was the toughest vagina in the animal kingdom.

I'm most impressed with the mind control abilities of the Penis. Man, the things it makes humanity stick it in, ridiculous.

But don't worry, you need not sever your penis to free your mind from such tyranny. Impotence is the key my friends.
