Duck Dynasty's Jase Robertson has always been outspoken about his Christian faith, and in his new memoir, Good Call: Reflections on Faith, Family and Fowl, the Louisana-native reveals he remained a virgin until his wedding night in 1991.

"I'm proud of that," the 44-year old says, confessing, "That was the hardest thing I've ever had to do in my entire life."

Now married to wife Missy for 23 years, the reality star shares his straight-forward approach to dating.

"What I did was when I started dating girls I would quickly tell them on the first date as soon as they got in the car," Jase says of discussing his abstinence.

"I'd say, 'Look, I will not treat you inappropriately at any point in our relationship.' I had a couple get out of the vehicle!"

Though some women weren't enthused by his methods, his future wife didn't seem to mind! "Missy was the first girl that loved that. She was like, 'Ok this is awesome,'" says Jase.

And although they had similar values, Missy's more privileged background caused a few to question her choice in men.

"In the book, I don’t think it accurately depicts the amount of persecution she suffered over dating me," the Duck Commander COO confesses. "They were on her. Even in front of me they would make jokes."

But Missy held steadfast throughout the bullying. "I think she saw that I didn’t care what people thought about me," shares Jase. "I was surprised that it didn’t bother her because they really heaped a lot of abuse on her."

The father-of-three also opens up about his decision to abstain from alcohol until he was 30 after watching father Phil Robertson struggle with substance abuse.

"I’ve never been high or drunk in my life," Jase tells Fox. "As much as I would like to say it was a spiritual decision, it was really a decision I made from monitoring my dad when he rented the bar…and I thought, 'Whatever they’re doing, I’m just not going to do that.'"

He continues, "I made a decision to wait before I drank any alcohol till I was around 30 because I just thought, 'I want to be mature enough to exert self-control.' Now I’ll have an occasional drink. It’s not something that I’m into."
