A sex toy went missing and we found it in our teens room? How do we address this?

So, the title pretty much says it all. My (44F) husband (49M) and I were cleaning and noticed a certain sex toy missing from it's normal place in the bottom nightstand drawer. We looked in all the other drawers, under the furniture, and in weird spots in our bedroom we knew it wouldn't be. For context, these things never leave our bedroom. The furthest they travel is into the attached master bathroom. Once we literally had no other place to look, we went into our daughter's room (14F) while she wasn't home and began searching. We found it hidden in a dresser drawer. We left it in place but realize we need to have a conversation with her. I was raised in a very strict, very religious house. You didn't talk about sex. You weren't even supposed to think about it. I've never punished or reprimanded our daughter or her siblings for asking questions. We used the real names of body parts when potty training. But it's not like it's a frequent (or ever) topic of discussion. How do I/we talk to her about this? Should it be one of us or both? What the hell do we say? This is not in the parenting books. I'm completely at a loss and have no idea what to do. via /r/Parenting https://ift.tt/2DgszqF
