Husband has low sex drive?

Hi we are newlyweds we have been together for 7 years and married for almost 3 months. My husband is away a lot for work he's a medic so he works 3days on and a couple off. He is constantly running and always on the move. We have sex maybe 3 times a month.. 😥 I just know that my sex drive is very high. And his doesn't seem like it used to be. We used to have sex everyday but now it's maybe once a week if I'm lucky. I know he's away a lot and time has a lot to do with it too. And no he isn't cheating or watching porn or mastirbating too much. We are also young, 24 years old so I don't think it has anything to do with any health issues. Am I alone in this boat? He doesn't like talking about it or setting or naughty pictures , I am just confused as to what I need to do. Sometimes I feel like I'm failing as a wife..😢 he's an all around amazing person, loves me and takes care of me. I just can't get over this one. I wouldn't say I'm ugly or fat and I'm very clean.. I just don't know. I am successful at my career and I would say I'm confident. He is also a very confident person, extremely professional and successful. Please help... I just want to feel wanted and woman enough for him. My confidence lowers everytime I get rejected or he doesn't make a move. I always have to make the first move. Most of the time when I get rejected he'll say "don't you ever just want to cuddle? Isn't that nice too?it doesn't always have to be about sex"
