I need help with my mom

So my mom keeps asking me why I’m going in her restroom more than mines. And I try to lie and say I like using her soap more than mines but I think she’s starting to not believe it. And I’m actually masturbating in her shower head in her restroom. My shower head doesn’t feel the same way in mines. And she’s very religious and will probably shame me. Like when I applied for a amazon card for a vibrator and she found a paper with the vibrated I wanted. What to do and please help. Oh and before you say use my own restroom the water pressure isn’t the same and it just feels weird.
