Cooper Koch wasn't wearing a prosthetic in that Monsters nude scene—that was ALL him

In one scene in the show, Erik is seen in the shower, and Koch spilled some pretty huge tea. The show was counting down iconic nude scenes, when Mark Wahlberg's famous scene in Boogie Nights was brought up.

"Just to say, mine was not a prosthetic," Koch said, smiling and pointing into the camera.

"Well, that was going to be my next question," Cohen replied. "Congratulations to you, Cooper! You're very blessed, aren't you?"

"Well hung," Koch smiled.

Koch was also asked if he has a boyfriend, to which he replied with a smile, "I do have a boyfriend, so sorry!"

He was also asked if it was true that he had an acting teacher who said he wasn't booking roles "because he has a gay voice."

"Um, yeah, that's true," Koch said, "Yes, it is true, yeah."

"That's so mean and homophobic!" fellow guest Finneas added in.

"Yeah, I don't talk to them anymore. I was so stunned by it at the time," Koch revealed. "It was before the class even started, and then I had to go through the class! Actually I'll add more to the story: she then proceeded to tell the entire class the conversation that we had and then all the students were looking at me like, 'oh my god,' 'awww.' Crazy, yeah."

"But then I can flip it on and off," while lowering his voice, "like, 'what's good bro, how are you,'"

"You'd never know," Finneas joked.

While Koch has been a pleasant breakout from the show, Monsters has also attracted a lot of controversy, particularly around the way it portrays the two Menéndez brothers' relationship.

The show insinuates that the brothers had a relationship that was incestuous and sexual, but there is no evidence that was the case at all.

In actuality, the brothers were the victims of incestuous abuse from their father, who mentally, physically, and sexually abused them throughout their lives before they killed him and their mother.
