preening rod
A penis that, though it may aesthetically pleasing, falls short of it's intended use. A nice, big, perfect dick that is governed by a man who is so incredibly useless that it is never allowed to reach anywhere near Its potential effective use thus rendering it a beautiful tragedy. Like a hot nun or nipples on a man.
"He couldn't make me cum even after 2 and a half hours of fucking".
"Sometimes the show cock turns out to be a preening rod."
