My bf doesn't want sex

My bf of a year is an amazing man who's very sweet. He takes care of me, has amazing communication skills, helps out around the house, and is genuinely one of the best men I've ever met.

But his sex drive is abysmal. Man doesn't even masturbate, even when I encourage it. (We live together so I thought he'd at least ask for some privacy or go to the bathroom or whatever for it at least once) And when he does want to have sex, it's once every month or so. Meanwhile, I want sex at least once every other day.

I love him so much but it's kinda killing my sexual confidence and though we've talked about it and he says he's working on finding ways to up his sex drive, it just doesn't feel like anything is changing (it's been 3 months after bringing it up). I feel so pent up and sexually unwanted, even though he legit tries to make me feel attractive (spankings, squeezing, kissing, etc. every day)

Idk what to do. But I hate feeling like this when we love each other so much.
