Purity balls, in which a girl pledges to remain "pure" until her wedding day and promises her father that she will remain a virgin until she's a wife, have become a phenomenon in America, taking place in 48 out of the 50 states.
Resembling giant wedding ceremonies, the purity balls see the girls - all around the age of 12 - wearing white "wedding" gowns and being presented with purity rings, which they wear to symbolise their commitment to their virginity.
The father and daughter will then share vows together, with the father saying: "I ………’s father, choose before God to cover my daughter as her authority and protection in the area of purity.
"I will be pure in my own life as a man, husband and Father.
"I will be a man of integrity and accountability as I lead, guide and pray over my daughter and my family as the High Priest in my home.
"This covering will be used by God to influence generations to come."
In the movement purity means no sexual contact of ANY kind, including kisses, until after marriage.
A new documentary on Nightline Prime follows families taking part in the ritual, focusing on father Ron, who is the head pastor at the Living Stones Church.
We see him kneel down in front of his younger daughters, presenting her with a purity ring and saying: "One of things I think it’s important to remember is this is your desire to do it the Lord's way and really save yourself from kissing lots of toads along the way and wait for your prince charming to come along.
"This is just a reminder that keeping yourself pure is important. So you keep this on your finger and from this point you are married to the Lord and your father is your boyfriend."
He then places the ring on the fourth finger of her left hand - her wedding finger.
While some might praise this idea for protecting the innocence of young girls, we can't help but feel this has been taken too far.
Rather than teaching young girls about safe sex, teen pregnancy and the dangers of STDs, it bans them from sex entirely - and we all know how appealing banned activities are for rebellious teens.
There also seems to be a lot of pressure on the young girls to go through with the ceremony - whilst nothing is said about the purity and innocence of young boys.
Do you think it is appropriate for a father to take on the role of their daughter's "boyfriend"? Do you think it is sensible to ban children and teenagers from kissing, let alone sex? Do you think this is an idea you'd like to see brought to the UK?
