I just don't get it

Really I just don't understand why is he never horny ever ? I'd fuck him day and night , until I can't walk . And yet he has no drive. I'm so tired of feeling unwanted and undesired . So frustrated that he doesn't even try . How does this even happen ,why does this happen ? He never wants it .I always have to start it and I'm just to that point to were I don't even know what to do. Can't say he is cheating or its stress he just doesn't want me and it hurts because I know he loves me he just doesn't even try . I'm not even asking for amazing sex . I just need to be touched needed and I'm at the end of the road lost confused .
