My 30 year old husband has never pleasured himself?

My husband and I have been together for 8 years and got married 1 year ago. He’s great in bed, but it’s just strange he’s never pleasured himself. He’s also not gotten himself off when I’m on my period. If I give him a bj he’ll cum, but he won’t finish himself off manualy with me giving him a BJ. We went on a trip a couple years ago and while I was sleeping he had a wet dream. I’ve asked him about it and he said it just never occurred to him to do it. I’ve confronted him about it and he’s said he’s never felt the need to. I told him he needs to communicate better and let me know if he needs to be pleased, and he got mad and said I shouldn’t expect him to communicate if he needs to be pleased sexually bc I don’t communicate that either. But I do communicate, I tell him I’m horny a lot ? idk, it just annoys me bc I’ve never met a guy who’s never masturbated before.
