Dickshark (2016)

In this movie, WOMEN are the ones who say, "Don't use your teeth!"

Rachel Crow stars as the woman whose lover has been secretly using penis-enlargement cream. It has an unusual side effect that ultimately leads to an abomination. Erin Brown (also known as Misty Mundae) supports her boyfriend, Dick (played by Bill Zebub) who is a modern day Victor Frankenstein. The search for the rampaging monster intensifies as more victims fall prey.
