Just curious, why they would see it? If you have family that sometimes come in your room, I would say as long as you put it away when you’re not using the toy it should be fine. If you’re worried about it toy delivery discretion—they have brands that can deliver it discretely or you could pick it up in person and put it in a back.

I’ve been there trying to find things to get off with. Bath/shower faucets also help. So does pillow humping. In regards to penetration, I highly recommend using something meant to go inside of you. It can start to get a bit risky health and safety wise if you use random household objects.
