4 year old found my dildo

No harsh comments please. I feel bad enough, just seeking advice.

My 4 year old found my dildo in my underwear drawer. She’s opening all drawers lately it seems, just exploring I guess. I have the dildo in the black silk bag it came in, but she opened and saw it. She asked if it was a mermaid 🤷🏻‍♀️. Then out of the blue, she asked if it’s for my butt. 🤦🏻‍♀️

What would you say/do in this situation?
