HUSBAND REFUSE SEX

I’ve been married for more than a year. My husband never initiate intimacy. I have to tell him everytime, lets do it. As if he is never interested. When we do it also, he lasts like 30 seconds and doesnt want to do it again. I feel so sexually unsatisfied. I love him, i dont want to leave him or cheat on him. But i feel so depressed. we have fought over this so many times. this breaks my heart. If i dont ask for sex to my husband, then to whom?! We get intimate like once a week or once in 10 days. Still when i ask him for more, he tells me to use my fingers. As he also masturbates. I feel digusted. I have tried it all to boost his desire, but nothing. I thought maybe he has low libido, but his ego doesnt allow him to visit a doctor or to take medecine. Beside that, we live like best friends. we do everything together. And yes he doesnt have any friends, or affair. Since we work together, and wherever he is, i am always informed. We dont have kids yet. and i dont think we will. Pls share your experience if you have ever been through. Am i over reacting? Do i have to shift my focus?
