Addicted to my shower head

Hi, i need some help, i think i got addicted to my shower head. I started masturbating in the shower ca one year ago and recently it started to really brother me. I have a perfect husband but somehow i made myself desentialised to his efforts and just prefer the quick daily realese in the bathroom. It all got to the point that we basicly live in a sexless marriage because of it.

It all started ca one year ago when he was stressed because of his work and had some issues with libido (mild ED). I always had high sex drive and discovered that i can get what i want using the strongest setting on our shower head. After a couple of months when all the mess at his job resolved itself he got better and things started to work again for him but stopped for me :/

No matter what he is doing and how hard he tries i cant reach an orgasm during sex. Doing it in the shower became a daily thing for me and because i'm "one and done" type of girl i reject him pretty all the time and i feel really bad about it. During last two months he stopped even trying to initiate. I feel like it will ruin my relationship.

Has anyone here had similar problem? How to gain my sensitivity back. I quit it two weeks ago and i still cant get myself off using my fingers. Even my Vibe feels like nothing.

How do i tell him what's wrong with me. I feel so embarrassed.
