Help! I need tips

I normally masturbate using an electric toothbrush (covered with something like Saranwrap or a condom). I’m never home alone so I don’t get much chances to masturbate. I love the feeling of an orgasm, but I need new ways to get to that. Rubbing my clit just doesn’t do it for me. And the shower head is out of the question because I cant detach mine. I need more ways to stimulate my clit and orgasm, but quietly so no one in my home knows! We have thin walls. Any suggestions?
