Positions & items

Hey, so I’ve been masturbating for 3 years. Mostly standing up in the shower with the shower head on my clit (feels amazing btw). Or in bed on my back fingering myself. Any ideas of 1. household items I can stimulate myself with (no dildos or vibrators or toothbrush handles)?

And

2. new positions I could try?

I am under 18 so I can’t buy dildos or vibrators, and I live with my family, so no vibrating toothbrushes.
