Two guys discuss their ideal penis size and what they think makes the "perfect" penis in a new Buzzfeed video.

After describing the things they don't like about their penises and drawing some doodles of the members they'd like to have, the guys are given dildo replicas of their dream penises to strap on and walk around the room for a test drive.

Science tells us the average global penis size is somewhere around 5.57 inches (unless you're German!), but reality tells us that men everywhere think that's still too small.

"I actually kind of would like to have a 12-inch penis," the gay guy says before seeing what an actual 12-incher looks like. "I've seen so much gay porn that I think this is the ideal size."

The straight guy similarly would like something like "what a porn star would look like," but his jaw drops to the floor as soon as he sees his vision in real life.

"I don't think this is ideal for me," he says while strapping on the giant package and swinging it back and forth between his legs. "I mean, how would you even walk around?"

"This is a lot to handle, this is a lot to deal with," he adds. "It definitely will change your life."
