How do I stop my mom from interfering with my masturbation habits?

She'd do things like wash my bedsheets whenever I cum on them, almost like she checks every day, and buy me new lube when I'm almost out, and regularly put new tissue boxes on my night stand, and replacing the trash bags.
She'd do these things when I'm off to school, and every time I come back to a new bottle of lube, or fresh sheets, etc. I feel dead inside.
My mom obviously knows I'm a coomer, and she's helping me out.
I feel so fucking embarrassed with myself. Should I even get her to stop? Is she actually going to far? Am I overthinking this?
