Kirk likes to show off for his girlfriend.
He's 23, lives on the east coast, and has been with her for about five years.
"She knows I'm out here," he said. "And she's all about it. It turns her on."
So they're kind of a wild couple.
"She likes to be curious with other girls from time to time," he said. "And I get to sit back and watch."
"So will she be watching your video?" we asked.
"Oh yeah," he said. "She will!"
