The Heart to Heart™ program, created by jeweler Joe Costello, differs from other abstinence programs in some important, unique ways. [...]

First, the "key to her heart." This beautiful heart has a smaller heart in the front. Behind that heart is a keyhole. When making the covenant with your daughter, you explain that the covenant is between her, you and God. Since God has placed her in your care as a parent, you and only you can hold the "key to her heart."

God not trusting her enough to let her be responsible for her own heart.

You then explain to the child that you will hold the key to her precious heart until the day of her wedding. On that day, you will give her away like at all weddings, BUT in doing so you will also “give away” the key to her heart to her now husband. The key and lock are actually functional and your son-in-law will place the key in the heart to open it.

Nothing at all Freudian going on here!

Inside will be a small note that had been placed in the heart on the day you made the covenant. That note can say something like, "I do not know your name or what you even look like, but this is my promise to save myself for you this day. Love, Melanie."

Or, the note could say something like, "I've been saving myself for you for many horny years, so the sex tonight had really better be worth it!. Oh, and make sure my Dad gives you the key to my chastity belt too. Love, Melanie."
