My sexy daughter wants me to buy a chastity belt for her

My 19 y/o daughter is getting married in a couple months. She wants me to buy a chastity belt for her so that I can lock it up and take the keys with me after the wedding. I think this is a sweet gesture but feels like a bit of a joke. She's the one who's been against sex before marriage. Help me.<br><br>PS: I am not interested in my daughter sexually. She's just a good girl who wants to stay a virgin until marriage.
