My daughters using my dildo

Im a single mom and therefore I have a rampant rabbit and two other dildos. I know my daughter is using the rabbit that I have because its not in the same position in my drawer and sometimes I come home she’ll be in her bedroom and if i check the rabbit will be missing. when I check later its back where i keep it.
shes only 15 and i thought maybe I should get her own but im worried because she is so young. anyone else have this situation and can offer advice please

Buy her one of her own. She is obviously enjoying using yours so why not get her one she doesn't have to share.
I bought my daughter one when she was 14. She knew all about using it. I put a ribbon on the box and left it on her bed one day with a note saying Have Fun! She found it when she got home from school. She came downstairs and told me I was the coolest mom ever and gave me a big hug. Better than her having sex with a bunch of different boys

Teenage masturbation is very normal. If you don't like her using your toys then take her out and buy her one of her very own, but first you should probably have a very candid, casual and intellectual conversation with her about masturbation. Tell her you know that she's been using your toys and that masturbation is normal for both boys and girls. Maybe get on the internet and show her the different types of "toys" available and explain what each one does. Her masturbating and playing with "toys" is better than her getting pregnant.
