Sex isn't the only thing forbidden in Ciara's house.

The R&B singer has taken a vow of celibacy with boyfriend Russell Wilson until the two eventually tie the knot. The Seahawks quarterback hasn't popped the question yet and the couple's willpower has been tested, but they remain loyal to their goal with religious beliefs serving as the driving force.

Much like Ciara and Wilson won't be getting it on in her home, she also has a rule against swearing.

"He's at the stage where he's repeating everything you say," the singer told Us Weekly on Saturday. "I learned that in a funny way the other day. He was like, 'shoot' and 'dang,' and I was like, 'What is that?' As long as he's not saying any of the other words that come behind a 'D' and an 'S'!"

Russell Wilson Is Obsessed With Ciara

Ciara is trying to set a good example for her son, who she welcomed into this world with her ex-fiancé, rapper Future, in May 2014. Future Jr. has a great relationship with Wilson, but it doesn't mean that Ciara necessarily eventually expects him to follow in their footsteps when it comes to abstinence.

"I just want for my son to be with the right person when the time comes," she said. "I know I can't call the exact path or direction he's going to walk in life, but I am hoping he walks in the right direction and I'm hoping more than anything that he'll be a gentleman."

Part of helping him become a gentleman includes keeping dirty words out of his mouth -- and openly staying out of the bedroom.
