The 35-year-old actor, who married actor Lauren Parsekian last year, said he had a "sheltered upbringing" and rarely dated during his teenage years, reported Contactmusic.
"It was a beautiful, loving home. I was very protected. They wanted to keep me out of harm's way, so I didn't grow up going to parties in high school," Paul said.
"I never dated. My main focus was school and theatre. I was just a theatre geek," he added.
Paul was smitten with Lauren from the minute they got together at the Coachella festival in 2011.
