Welcome to that special corner of BuzzFeed where we talk about nudity and penises. If you're here by mistake, now would be a good time to navigate away as today we're talking about on screen D.
We can all think of a time when an actor has bravely displayed his appendage in a TV show or film, but choosing whether to go with a specially made ~fake~ wang, or using what god gave you is a pretty big decision that will follow you for life.
So, without further ado, allow me to present you with 11 examples of when an actor opted for a prosthetic penis, and 10 times they said "fuck it, let's do this for real"... or something to that effect.
PLUS, the reasons behind their decisions (so this can be called "academic").
