"That took a lot of prayer," the 33-year-old admitted to InStyle in an interview published on Wednesday. "It was hard. I can't lie."
The star, who graced the fashion magazine's April cover issue, previously spoke about her and Wilson's decision, noting that "you shouldn't feel like you have to give your body away to get someone to like you."
"It's important to have a friendship," she told Cosmopolitan South Africa in 2017. "It's important to have standards."
Ciara went on to reveal that she and Wilson, 30, sat down when they first started dating to have a "conversation" about the "intimacy part" of relationships.
"I have to give credit to my husband for sharing those views," she told the news outlet at the time. "It's awesome how it all worked out."
Following the pair's March 2016 engagement, the Seattle Seahawks quarterback and the "Level Up" singer tied the knot four months later at Peckforton Castle in Cheshire, England.
The happy couple welcomed their first child together, daughter Sienna Princess Wilson, in April 2017. Ciara is also mom to 4-year-old son Future Zahir with ex Future.
