Low sex drive

My husband has a low sex drive. He has for a while. He acts like more than once a week is exhausting and im kind of over it. I'd be happy if it was even 2x a week! Right now its only like 2-3x a month. I'm tired of masturbating. I just want the D but I guess im apparently not fucking good enough -.- And when we do have sex its like 3 min and he barely even tries to get me off. Im about to combust over here!
