Oral in need 😩

I’ve been with my husband for years and he’s never really been one to go down on me but loves when I do it to him I’ve asked him about it and he says he doesn’t like to do it because he doesn’t know how and I just wanna scream I need more during sex and he’s like blow me and that’s it I’ve asked if I smell or taste nasty and he says no like I’m sure I’m clean and he still doesn’t. This is starting to become a problem because I’m not getting off with sex and I’m over it but he still won’t do it 😩 I just wanna sit on his face but he doesn’t like it.
